Question 15-18 are all apart of the same question. Please answer them all. Thank you

The Goliath is a new wooden roller coaster that allows the riders to go upside-down on the loop shown
below. The starting height of the coaster is 95.6 m. The radius of the loop is 24.4 m. Riders board the cars
at A. The car is drawn by a chain up to the point B and then released from rest. Gravity does everything
from then on through the points C, D and E!
