A railway truck of mass 8,000 kg travels along a level track at a velocity of 2.5
Question:
A railway truck of mass 8,000 kg travels along a level track at a velocity of 2.5 m s–1 and collides with a stationary truck of mass 12,000 kg. The collision takes 4.0 s and the two trucks move together at the same velocity after the collision.
What is the average force that acts on the 8,000 kg truck during the collision?
A. 2000 N
B. 3000 N
C. 5000 N
D. 12,000 N

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
