Two objects roll down a hill: a hoop and a solid cylinder. The hill has an elevation change of 1.4-m and each object has the same diameter (0.55-m) and mass. Calculate the velocity of each object at the bottom of the hill and rank them according to their speeds. [Hint: When an object is rolling, the angular speed and the velocity of the center of mass are related by , where is the radius of the object.] Veyi= 4.3 m/s...

A bicycle and its owner roll down a hill dropping in altitude 4.0 m, ending up on level ground. The mass of the cycle plus bicyclist is 70.0 kg. We ignore the effect of friction in the first two questions. A. If the bicycle starts initially at rest, find the speed of the bicycle when it reaches level ground. B. If instead the bicycle starts with an initial speed of 4.0 m/s, find the speed of the bicycle when it...

A group of kids are racing hula hoops down a hill that is 0.8 m high. One hoop is .7kg with a radius of 67 cm and the other hoop is .5kg with a radius of 43cm. If both hoops are initially traveling at 1.2 m/s right after they are pushed off the top of the hill, what hoop will reach the bottom first use the conservation of energy to support your answer. What is the change in angular momentum...

A box is sliding down a spherical hill. The hill radius is R=1 km. The ball starts with zero initial velocity. There is friction between the box and the hill surface The box slips off the hill when the line connecting center of the Hill to its position is at angle θ=10 degrees. What is the speed of the box at this point right before it detaches from Hill? How much energy is lost due to friction while the box...
