Question

write a description of what you think will happen if a car at rest is hit by a second car of equal mass moving toward it with a speed v, assuming the cars do not stick together. write a description of what you think will happen if a car at rest is hit by a second car of equal mass moving toward it with a speed v, assuming the cars do not stick together. write a description of what you think will happen if a car at rest is hit by a second car of equal mass moving toward it with a speed v, assuming the cars do not stick together.

Explanation / Answer

let the mass of car = m

speed of the car = v

initial momentum = mv

final momentum = m(v1 + v2)

by conservation of momentum

mv = m(v1 + v2)

v = (v1 + v2)

so after collision both the cars will continue to move in same direction as the first car but its velocity will be reduced, and another car's velocity will be increased by the same amount.
