I'm working on completeing a physics assignments and have found myself lost. Here is the information I have been given:
Car 1 approached the intersection from the top of a 25-meter hill.
∙ Car 2 was on a flat stretch of road directly in front of Car 1.
∙ At the bottom of the hill, before braking for the stop sign, Car 1 was going 20 m/s
and Car 2 was going 30 m/s before it stopped at the stop sign.
∙ From the skid marks on the road you can see that Car 1 applied force on its brakes
for 3 seconds, 100 meters before the stop sign.
∙ There were 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 800 N of force, 10 meters off to the side of the road so
no one else gets hurt.
I have run out of characters to use, so if you can help me, PLEASE email me!
