Question: A cart is pushed up a ramp with an initial speed vo = 2.5 m/s. For this problem, you may assume that the cart is frictionless and the acceleration of the cart a = g sin ?
a) If the angle of the ramp ? = 20°, what is the maximum distance d that the cart will travel up the ramp?
b) If is increased to 45°, what is the maximum distance d that the cart will travel up the ramp?
