The initial speed of the6) A roller coaster cart of massroller coaster is 10 m/s.Ah = ?Ax = 20ma) If it reaches the top of the next hill with a speed of 15 m/s, what is the vertical distance between thetops of the two hills? Assume that friction is negligible.b) If the distance from the top of the first hill to the ground is 3 times the vertical distance you found inpart a, what is the speed of the cart once it reaches the ground?c) At the end of the ride, the cart is brought to rest from the speed that you found in b). How muchwork was done to bring the cart to rest? How far did the cart travel before coming to rest if the coefficientof kinetic friction is µk = 0.6.d) What average force was delivered to the cart during this time if the cart was stopped in 20 meters?
