a) Assuming no energy is lost and using energy arguments, howfast is the cart moving at point C?

b) What is the total mechanical energy of the roller coaster atpoint B (Use the ground as the locaiton where potentialenergy=0)

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
