Answer:

The time taken for the ball to get to the batter is 0.41 s.

Explanation:

Given;

initial velocity of the baseball, u = 45 m/s

horizontal distance between the pitcher and the batter, X = 18.39 m

The horizontal distance or range of a projectile is given as;

X = ut

where;

t is the time of flight

u is the initial velocity

t = X / u

t = 18.39 / 45

t = 0.41 s

Therefore, the time taken for the ball to get to the batter is 0.41 s.

Answer:

Yes the student is correct

Explanation:

The first law of thermodynamics states that energy can neither be created nor destroyed

The second law of thermodynamics states that the entropy (disorderliness) of an isolated system always increases

Therefore, whereby energy is not supplied to maintain the orderly oscillatory motion with constant amplitude, the amplitude of the system is bound to reduce with time that is the vibration of the system must be damped

Answer:

Change in velocity = 4 m/s and acceleration = 0.5 m/s²

Explanation:

Given that,

Initial velocity, u = 3 m/s

Final velocity, v = 7 m/s

Time, t = 8 seconds

(a) The change in velocity of a cyclist.

[tex]\Delta v=v-u\\\\=7\ m/s-3\ m/s\\\\=4\ m/s[/tex]

(b) Acceleration,

[tex]a=\dfrac{\Delta v}{t}\\\\a=\dfrac{4\ m/s}{8\ s}\\\\a=0.5\ m/s^2[/tex]

So, the change in velocity is 4 m/s and acceleration is 0.5 m/s².

True is the correct answer

Answer:

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second units are newtons per square meter, or N/m2.

Explanation:

Do you not feel the pressure when mass is on you?

Answer:

well a beach ball could be any size at all a bowling ball is usually the same size  the weight difference is inside of them inside the beach ball there's air although in a bowling ball there's cement or rock i don't know what they put inside the ball but anyway the bowling ball a lot higher density o it has more volume so the bowling ball is a lot heavier than just a beach ball

Some of the names of the basic quantities include:

Answer:

The value is [tex]T = 122036.2 \ N[/tex]

Explanation:

From the question we are told that

     The mass of the car is  [tex]m = 6526 \ kg[/tex]

      The acceleration  is  [tex]a= 8.9 \ m/s^2[/tex]

Generally the net force applied on the rope is mathematically represented as

          [tex]F_{net} = T - W[/tex]

Here W is the weight of the car which is evaluated as

         [tex]W = m * g[/tex]

=>      [tex]W = 6526 * 9.8[/tex]

=>       [tex]W = 63954.8 \ N[/tex]

Generally the net force can also be mathematically represented as

       [tex]F = m * a[/tex]

So

        [tex]m * a = T - 63954.8[/tex]

=>     [tex]6526 * 8.9 = T - 63954.8[/tex]

=>      [tex]T = 122036.2 \ N[/tex]

Answer:

Answer: B. 49 N

Explanation:

Friction Force

When an object is at rest on a rough surface, it encounters a friction force that opposes motion.

The friction force when an object is moving on a horizontal surface is calculated by:

[tex]Fr=\mu_k N[/tex]

Where [tex]\mu_k[/tex] is the coefficient of static friction and N is the normal force.  

If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal are equal in magnitude:

N = W = m.g

Thus, the friction force is:

[tex]Fr=\mu_k W[/tex]

We are given the coefficient of static friction [tex]\mu_k=0.5[/tex] and the mass of the object m=10 Kg. The minimum force needed to make it start moving is the maximum friction force:

Fr=0.5*10*9.8

Fr = 49 N

Answer: B. 49 N

Answer:

stainless steel is the material which is non magnetic.

Answer: 1. It always acts in the direction opposite to the direction of motion. 2. It's magnitude is equal to that of the force trying to set the object in motion only until it starts to move.

Explanation: Properties of frictional forces:

1. Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. 2. Frictional forces are caused due to intermolecular interactions between the bodies.

Explanation:

force is a force between two surfaces that are sibling

1. it acts parrell

2. it is caused due to intermolecular interactions between two bodies

Uniform circular motion is defined as the constant-speed movement of an object in a circle.

The definition of speed is. The rate at which an object's position changes in any direction. Speed is defined as the ratio of distance traveled to time spent traveling.

Speed is classified as a scalar quantity because it has only one direction and no magnitude.

In summary, the act of turning away or in the opposite direction. reversal, reverse, reversion, turnabout, turnaround.

Answer:

(a) 100.38 m

(b) 183.49 m

(c) 6.12 seconds and 12.24 seconds.

Explanation:

Given that a body is thrown vertically upwards with a velocity of 60 m/s.

Assuming that upward direction is positive

So, the initial velocity, u=60 m/s

As the acceleration due to gravity, g=9.81 m/s^2, acts in the downward direction, so

a=-9.81 m/s^2

(a) By using the equation of motion, the displacement of the body after time t=2 seconds, is

[tex]s=ut+\frac 1 2 at^2 \\\\ s=60\times 2 +\frac 1 2 (-9.81)2^2 \\\\[/tex]

s=100.38 m

Hence, the height of the body will be 100.38 m after 2 seconds.

(b) At the maximum height, the velocity of the object is zero, so

v=0.

The maximum height is the displacement of the body where it attains zero velocity.

Using the equation of the motion.

[tex]v^2=u^2+2as \\\\0= 60^2 +2(-9.81)s \\\\s=\frac {3600}{2\times 9.81} \\\\[/tex]

s=183.49 m

Hence, the maximum height of the body is 183.49 m.

(c) Time to reach the maximum height

v=u+at

0=60 +(-9.81)t

t=60/9.81

t=6.12 seconds.

The body will take 6.12 seconds to reach the maximum height.

As the time to reach the maximum height from the initial position is the same as the time to reach the initial position from the maximum height.

So, the total time to returns again to the place where it was launched

= 2 x 6.12 = 12.24 seconds.
