A small block of mass M = 0.10 kg is released from rest at point 1 at a height H = 1.8 m above the bottom of a track, as shown in the diagram. It slides
down the track and around the inside of a loop of radius R = 0.6 m. The speed of the block is 2.5 m/s at point 3. Which of the following claims about the
situation is correct?
A) The gravitational potential energy of the block-Earth system at point 3 is less than the gravitational potential energy at point 2.
B) The kinetic energy of the block at point 3 is greater than the kinetic energy of the block at point 2.
The mechanical energy of the block-Earth system at point 3 is less than the mechanical energy of the block-Earth system at point 1.
D
The mechanical energy of the block-Earth system at point 2 is equal to the gravitational potential energy of the block-Earth system at point 1.
