A 3 kg block (block A) is released from rest at the top of a 20 m long frictionless ramp that is 4 m high. At the same time, an identical block (block B) is released next to the ramp so that it drops straight down the same 4 m. Find the values for each of the following for the blocks just before they reach ground level.

(a) gravitational potential energy

       Block A      ?

       Block B   ?

(B) kinetic energy
