A 960kg car is at the top of a 46m -long, 2.5 ? incline. Its parking brake fails and it starts rolling down the hill. Halfway down, it strikes and sticks to a 1210kg parked car.
Part A-

Ignoring friction, what's the speed of the joined cars at the bottom of the incline?

Express your answer to two significant figures and include the appropriate units.


Part B-

What the first car's speed would have been at the bottom had it not struck the second car.

Express your answer to two significant figures and include the appropriate units.

Solutions

Expert Solution

car A=960Kg

car B=1210 kg

It moves with the acceleration 23 m

When the car A strikes with car B

It moves with the acceleration 23 m

Part B

Above we have an acceleration and it is the acceleration without strike

it moves with acceleration 46 m

A ball rolls down from the top of an incline with a height of 5 m high without slipping. The ball has a diameter of 0.2m. What are the ball’s translational speeds a) at the center of the ball, b) at the contact point on the ground, and c) at the top of the ball when it arrives at the bottom? What values of "c" do you expect for hollow/solid balls? Will the hollow ball be faster?
