Question

A 2200 kg car moving east at 10.3 m/s collides with a 3160 kg car moving east. The carsstick together and move east as a unit after the collision at a velocity of 5.32 m/s. a) What is the velocity of the 3160 kg car before the collision?

Answer 1

Answer:

u = 1.77 m/s

Explanation:

Conservation of momentum

2250(10.3) + 3160u = (2250 + 3160)(5.32)

u = 1.77 m/s
