Question

Two blocks of equal mass are raised 10meters. One of them is placed on top of a long ramp, where it is released to slide down to the bottom. The other block is dropped from its raised height. Which one has the largest speed when it hits the ground? What if the ramp has friction?

Answer 1

(1/2)m v^2 = m g h for both
of course if you let it generate heat it will slow down

Answer 2

a. If the ramp is frictionless, their speed will be the same.
b. The block that was dropped will have the highest speed.
