In a truck-loading station at a post office, a small 0.4 kg package is released from rest at point A on a track that is 1/4 of a circle with radius 1.9 m (as shown in the below Figure). The size of the package is much less than 1.9 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 3.4 m/s.

In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m.
