- Suppose a 175 kg motorcycle is heading toward a hill at a speed of 34 m/s. The two wheels weigh 12 kg each and are each annular rings with an inner radius of 0.280 m and an outer radius of 0.330 m. a) how high can it coast up the hill, if you neglect friction in m? b) how much energy is lost to friction if the motorcycle only gains an altitude of 39m before coming to rest?Pls answer with handwritten solutionsThe figure below shows a ball with mass m = 0.322 kg attached to the end of a thin rod with length L = 0.454 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically up position, with zero speed there. (a) What initial speed must be given the ball so that it reaches the vertically upward position with zero speed? m/s (b) What then is its speed at the lowest point? m/s (c) What then is its speed at the point on the right level with the initial point? m/s

- A light rope is wrapped several times around a large wheel with a radius of 0.400 m. The wheel rotates in frictionless bearings about a stationary horizontal axis, as shown in the figure below. The free end of the rope is tied to a suitcase with a mass of 15.0 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.50 m/s when it reaches the ground. Calculate: What is the linear acceleration of the suitcase as it falls? (Hint: It’s not in free fall!) What is the resulting angular acceleration of the wheel? What is the angular velocity of the wheel when the suitcase hits the ground? What is the tension in the string as the suitcase falls?
