In a bumper car arena, two cars of equal mass are heading straight toward each other. the orange one is traveling at a speed of 5 meters per second. the green one is traveling at a speed of 2 meters per second. which of the forces most affects the motion of the bumper cars after they collide?

The force of orange car will affect the motion of the bumper cars after their collision.

Explanation:

Let the mass of both the car be 'm' travelling straight towards each other with time

Velocity of orange car = =5m/s

Velocity of green car = =2m/s

Force of orange car =

...(1)

Force of green car =

...(2)

From the above two expression of we see that Impulse is directly proportional to velocity. So, the car with higher velocity will be having impulse. When the orange car bumper car collides with green car the impulse of orange car will be more. With high Impulse the Force on orange car will also be more.

Hence,the force of orange car will affect the motion of the bumper cars after their collision.
