A small block, with a mass of 250 g, starts from rest at the top of the apparatus shown above. It then slides without friction down the incline, around the loop and then onto the final level section on the right.
The maximum height of the incline is 80 cm, and the radius of the loop is 15 cm.
a. Find the initial potential energy of the block
b. Find the velocity the block at the bottom of the loop
C. Find the velocity of the block at the top of the loop.
d. What is the normal force on the block at the lowest point of the loop?
e. What is the normal force on the block at the highest point of the loop?
