Textbook Problem

A car of mass m moving at a speed v1 collides and couples with the back of a truck of mass 2m moving initially in the same direction as the car at a lower speed v2. (a) What is the speed Vf of the two vehicles immediately after the collision? (b) What is the change in kinetic energy of the car-truck system in the collision?

(a)

To determine
The speed of the two vehicles immediately after the collision.

Explanation

Given info: The mass of the car is m . The velocity of the car v1 . The mass of the truck is 2m . The velocity of the truck is v2 . The car and the truck move in the same direction.

Explanation:

From conservation of momentum,

Pinitial=Pfinal

  • Pinitial is the initial momentum
  • Pfinal is the final momentum

The formula to calculate momentum is given by,

P=mv

  • m is the mass
  • v is the velocity

Hence from the conservation of momentum,

(

(b)

To determine
The change in kinetic energy of the car-truck system in the collision.
