Rotational EnergyYou and a friend are playing with a bowling ball to demonstrate some ideas ofRotational Physics. You put the ball on a hill of height 9.00 m where it is initially atrest. Then you allow the ball to travel down the hill. You do this on a sidewalk, sothere is friction and the ball rolls down the hill without slipping,A bowling ball can be modeled as a solid sphere rotating about its center. Thisbowling ball has a mass of 6.50 kg and a radius of 0.140 m. You'll need to look upthe equation for the Moment of Inertia in your textbook.At the bottom of the hill, what is the linear velocity of the bowling ball? This is aconservation of energy problem, but don't forget to include rotational kinetic energy!Your answer should have the following:2 Decimal PlacesCorrect SI UnitsAppropriate Signs for Vector quantity answersAnswers must be in the following format:Written out and NOT in scientific notationAcceptable: 278.40Not Acceptable: 2.784 x 102Your Answer:AnswerunitsOType here to search99+HomeEndDIIPrtScnFBF6F3%236.8.WRD

The objects shown here are a thin circular hoop, a spherical solid, a spherical shell, and a circular disk. The mass distribution for each object is uniform. If all four objects have the same mass and radius, which has the largest moment of inertia about its axis? 46 Select one: a. circular hoop b. spherical solid c. spherical shell d. circular disk
A 0.1 kg solid disc has a radius of 0.2 m. The moment of inertia of a solid disc is I = ½ m r2. EXAM The disc initially rolls with a velocity of 2 m/s along a horizontal surface. It then rolls up a ramp and briefly stops when it reaches a height h. The disc rolls without slipping on both surfaces. a) What is the angular velocity of the disc when it is on the horizontal surface? b) What is the speed of a point on the very top of the disc when the disc is on the horizontal surface? c) Use Conservation of Energy to find the maximum height of the disc, h. d) If the disc were replaced with a thin ring (same mass, same radius, same initial speed), would it roll higher, less high, or the same height? No calculations required. Briefly explain your answer! e) If there were no friction (the disc slides instead of rolling), but the disc still has the same initial speed, would it roll higher, less high, or the same height?
Conservation of Angular Momentum An example of conservation of angular momentum is jumping on a Merry-Go-Round. Watch this video (it starts part way through but the only thing you miss is the people pushing the Merry-Go-Round) to see someone jumping on a Merry-Gr-Round in motion like this problem. You can model the Merry-Go-Round as a solid disk with a radius of 3.00 m and a mass of 75.5 kg. Initially the Merry-Go-Round has an angular velocity 7.90 radians / second. Then the person jumps on and change the Moment of Inertia of the system. The person lands on the outer edge of the Merry-Go-Round and has a mass of 60.0 kg. What is the final angular velocity of the system after the person jumps on? You can treat the person that jumps on a point mass (which means they are significantly smaller than the radius of the Merry-Go-Round) for this problem.
