Please help me with these problems: 1) In a circus performance, a large 4.0 kg hoop with a radius of 2.0 m rolls without slipping. If the hoop is given an angeular speed of 6.0 rad/s while rolling on the horizontal and is allowed to roll up a ramp inclined at 15 degrees with the horizontal, how far (measured along the incline) does the hoop roll? 2) A wooden bucket filled with water has a mass of 75 kg and is attached to a rope that is wound around a cylinder with a radius of 0.075 m. A crank with a turning radius of .25 m is attached to the end of the cylinder. Wht minimum force directed perpendicularly to the crank handle is required to raise the bucket? Thanks in advance.
