Question


Toolkit

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.
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.
