a cart with a mass of 200 kg along a frictionless track.
a. Calculate the velocity of the cart at points A and C is the cart is dropped from a height of 100m with an initial velocity of 10 m/s.
b. Calculate the height of the second loop knowing that the velocity of the cart is 24.5 m/s at the top of the loop (point D).
c. calculate the total energy of the cart for any one of the points A through D.
