Question 1: The cart of mass, m, starts from rest at a maximum height, h, at the top ofa track. It will accelerate as it travels along the track, so that at the bottom of the track (where the height is zero) the cart is moving with a speed, v. Assume that there is no friction between the cart and the track in this situation
a. What kind of energy (potential, kinetic, both?) does the cart have at the top of the track? Describe in words and with equations.
b. What kind of energy (potential, kinetic, both?) does the cart have at the bottom of the track, where the cart is moving with a speed, vy? Describe in words and with equations. c. What kind of energy (potential, kinetic, both?) does the cart have in the middle of the track, when the height is h/2 and the speed is v? Describe in words and with equations.

Question 2: How would the total energy at each location (top, middle and bottom) change if there IS friction between the cart and the track? Describe the energy at each location with friction using sentences and equations.
