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.
1 answer
Since they are identical, they will have the same mass. With no friction, they both convert the same potential energy to kinetic energy, with no losses.
