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 car is parked on a cliff overlooking the ocean on an incline
that makes an angle of 19.0° below the horizontal. The negligent
driver leaves the car in neutral, and the emergency brakes are
defective. The car rolls from rest down the incline with a constant
acceleration of 3.06 m/s2 for a distance of 70.0 m to the edge of
the cliff, which is 40.0 m above the ocean.

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?
