If the mass of the truck is doubled, the force of friction is doubled, and the skidding distance is doubled.
Hence, the correct option is C.
The skidding distance is proportional to the mass of the truck. If the truck is heavily loaded so it has twice the total mass, the skidding distance will be twice as far.
This is because the force of friction is proportional to the normal force, which is in turn proportional to the mass of the truck. The greater the mass of the truck, the greater the force of friction, and the longer the skidding distance.
In equation form, the skidding distance is given by:
s = μ * d / f
where:
s is the skidding distance
μ is the coefficient of friction
d is the distance traveled before the truck stops
f is the force of friction
The force of friction is given by:
f = μ * mg
where:
m is the mass of the truck
g is the acceleration due to gravity
Therefore, If the mass of the truck is doubled, the force of friction is doubled, and the skidding distance is doubled.
Hence, the correct option is C.

speed?
A. 4.2 m/s
B. 2.5 m/s
C. 1.8 m/s
D. 3.6 m/s
Answers
Answer:
D. 3.6m/s
Explanation:
The equation for wave speed can be used to calculate the speed of a wave when both wavelength and wave frequency are known. Consider an ocean wave with a wavelength of 1.2 meters and a frequency of 3 hertz. The speed of the wave is: Speed = 1.2m x 3wave/s = 3.6 m/s

A force of 360 N [East] was applied by a student on a box with a mass of 50 kg.
What is the acceleration of the box if a frictional force of 340 N acts in the
opposite direction?
Answers
F = F⁰ - Ff
F = 360 N - 340 N
F = 20 N
F = m × a
20 N = 50 kg × a
a = 20 N / 50 kg
a = 0.4 m/s²
#LearnWithEXO
The acceleration of the box when the frictional force of 340 N is applied to the box will be 0.4 m/s².
What is acceleration?In mechanics, acceleration is the measure of how quickly the velocity of an object changes with respect to time. The magnitude of accelerations as a vector. The acceleration of an object depends on the direction of the net force acting on it.
It is a vector quantity because acceleration has both a magnitude and a direction. Additionally, velocity is a vector quantity. The change in the vector of velocity during a period of time divided by the period of time is the definition of acceleration.
According to the question,
F = F⁰ - [tex]F_f[/tex]
F = 360 N - 340 N
F = 20 N
Force = m × a
20 N = 50 × a
a = 20 N / 50 kg
a = 0.4 m/s²
So, the acceleration of the box will be 0.4 m/s².

Answers
Answer:
the blue bumper car
Explanation:
because the yellow bumper car is coming in with much more force
and according to Newton, actions and reactions are equal and opposite, so the yellow bumper car will five out 300N while the blue car will give out only 100N
then it almost because a fight between 300N vs 100N
