Question

A 1325-kg car, C, moving north at 27.0 ms-1, collides with a 2165-kg car, D, moving east at 11.0 m.s-1. The two cars are stuck together. In what direction and with what speed do they move after the collision?

Answer 1

Answer:

A 2.0 kg ball, A, is moving with a velocity of 5.00 m/s due west. It collides with a stationary ball, B, also with a mass of 2.0 kg. After the collision, ball A moves off at 30° south of west while ball B moves off at 60° north of west. Find the velocities of both balls after the collision.

Since ball B is stationary before the collision, then the total momentum before the collision is equal to momentum of ball A. The momentum of ball A before collision is shown in red below, and can be calculated to bep=mv=(2.00 kg)(5.00 m/s)=10.0 kg m/s west
