Question

Block A slides down a ramp whose slope is 45°. An identical block B slides down a ramp whose slope is 60°. Both blocks start at a height of 2 meters. Compare the kinetic energies (KE) of the blocks just before they reach the bottom, assuming there is no friction.

A) They are the same
B) Block A's PE is greater than block B's PE
C) Block B's PE is greater than block A's PE
D) The actual masses must be known in order to figure this out

Answer 1

The answer would be C. because as it says the potential energy is greater, so with that being said, the kinetic energy would be greater. Say you take two balls on with a greater slope than the other than the ball with the greater slope would go down faster, so its the same thing but just with blocks,
