Question

Two cars are involved in a head-on collision and come to a complete stop. Car 1 has a mass of 750kg, car 2 has a mass of 500kg. Car 2 was travelling at 15 m/s what was the velocity of car 1 before the impact?

Answer 1

Answer:

speed of car 1 was 10m/s

Explanation:

mass of car1 = 750kg

speed of car 1 = x

mass of car 2 = 500kg

speed of car 2 = 15m/s

cars come at rest after collision.

car 1 = car 2

750 × x = 500 × 15

750x = 7500

x = 7500

750

x = 10

therefore the speed of the car 1 was 10m/s.
