A bullet is fired horizontally at 343 m/s from the top of a building where height is 37.3 m. The built will be
in flight for seconds
Answer:
Explanation:
A classic projectile motion question. Horizontal motion does not matter whatsoever in the context of this equation as we are looking at the vertical component of velocity only. Since the question states that it is fired horizontally, there is no vertical component of velocity. Thus, v0y = 0.
Assuming the projectile is on the Earth, we can use the free-fall acceleration, 9.8 m/s^2.
The question gives us Δy, which is 37.3m.
Using the second kinematics equation, Δy = v0t + (at^2)/2, we can substitute in the values.
37.3 = 0 + 0.5(9.8)t^2
37.3 = 4.9t^2
7.61224489796 = t^2
t = 2.75902970226 seconds.
A mason is shot with a constant speed of 7.5 x 10²m/sinto a region, when an electric field produces acceleration on the mason of magnitude 1.5 x 1025 ms-2 directed opposite to the velocity. Find the time taken (b) the distance covered by the mason before coming to rest and (c) the time for which it remains at rest.
Answer:
Distance, d = 0.1 m
It is given that,
Initial velocity of meson,
Finally, the meson is coming to rest v = 0
Acceleration of the meson, (opposite to initial velocity)
Using third equation of motion as :
s is the distance the meson travelled before coming to rest.
So,
s = 0.1 m
The meson will cover the distance of 0.1 m before coming to rest. Hence, this is the required solution.

What is the car's acceleration
Answer:
The acceleration of the car was one meter per second squared.
Explanation:
We can use one of the kinematic equations:
[tex]\displaystyle v_f = v_i + at[/tex]
Where v_f is the final velocity, v_i is the initial velocity, a is the acceleration, and t is the time (in seconds).
The final velocity is 40 m/s, the initial velocity is 35 m/s, and the time is 5 s. Substitute and solve for a:
[tex]\displaystyle \begin{aligned}(40 \text{ m/s}) &= (35 \text{ m/s}) + a(5\text{ s}) \\ \\ 5 \text{ m/s} &= a(5\text{ s}) \\ \\ a &= 1\text{ m/s$^2$} \end{aligned}[/tex]
In conclusion, the acceleration of the car was one meter per second squared.

Which of the following statements accurately describe a scientific law?
there is no contradictory evidence in the current body of knowledge
it is an educated guess about how a process occurs
can be updated or rejected if any contradictory evidence is found
it is an statement that is true in many, but not all, cases
it is an observation that has been made many times
Answer:
The first statement appears most accurate.
The last statement also appears accurate, but it does not preclude any contradictory evidence.
The following statements accurately describe a scientific law: There is no contradictory evidence in the current body of knowledge. It is a statement that is true in many, but not all, cases. It is an observation that has been made many times.
The other statements do not accurately describe a scientific law:
"It is an educated guess about how a process occurs" describes a scientific hypothesis or theory, not a law.
"Can be updated or rejected if any contradictory evidence is found" describes the nature of scientific theories, which can be revised or discarded based on new evidence, but laws tend to remain consistent.

A student pushes a chair into a desk. If the student's push is the action force, then what is the reaction force in this example of Newton's third law?
A. the force that the chair exerts on the desk after it is pushed in
B. the force of friction acting on the chair
C. the force of gravity acting on the chair
D. the force from the chair on the student
Answer:
Ans : C
Explanation:
C. The force of gravity acting on the chair
Answer:
D. the force from the chair on the student
Explanation:
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.

Another unfortunate bug splatters on the windshield of a moving car. Which has the greater change in momentum---the bug or the car?
Answer:
The change in momentum for the bug and the car will be equal, impulses will be equal in opposite directions and the bug will have a greater acceleration compared to the car, because it has a smaller mass.

how much is the velocity of a body when it travels 600m in 5 minutes ?
its answer is 2M/S
but I don't know solution to take this answer

Time= 5×60 = 300 sec
Velocity= Displacement/time
= 600/300
= 2 m/s

The physical evidence are the silent witnesses against the perpetrators of a crime
The correct option of what the field inspector packages after the crime scene has been photographed is the option;
Physical evidenceReason:
Physical evidence are evidence that originate from inanimate objects or origin that is nonliving, and includes every material or object that serve as an indicator that someone has committed a crime, or that can link a perpetrator to crime
Examples include; Documents, hair, skin, fingerprints, weapons, soil, or fibers
The field inspector, collects the evidence that shows that a crime has been committed which are the physical evidence, after the crime scene has been photographed
