Know the answer to this question? Two cars equal mass (1,000 kg each) involved in a rear wnd accident at a stop sign. Here is what you know.

. Car 1 approached intersection from the top at 25 meter hill.

. Car 2 was on a flat stretch of road directly in front of Car 1

. At the bottom of the hill, Car 1 was going 20 m/s, Car 2 at 30 m/s before it stopped at the stop sign.

. There was no skid marks left by Car 2. The collision occurred at the stop sign, where car 2 had stopped.

. After the collision, both cars were moving together in the same direction at 10 m/s before slowly rolling to a stop.

. You must now push Car 2, using 800N of force, 10 meters off to the side of the road so no one gets hurt.

7) Assuming that there are no other nonconservatice forces involved, what inpluse was given to each car during the collision?

A. Car 1 -

B. Car 2 -

8. How many energy did Car 1 lose in the collision?

9. How much energy did Car 2 gain in the collision?
