A wheel with a mass of 0.8·kg and a radius of 0.35·m is pulled by a horizontal force applied at its center. The curb is 0.14·m high.
a) What is the minimum force needed to just raise the wheel off the ground?
b) Suppose the horizontal force you found in the previous part is increased by 4.2·N. If you model the wheel as a simple hoop, what is its initial angular acceleration as it starts to rise off the ground?
