bowler uses a lane with a coefficient of kinetic friction of 0.177.0.177. The bowler releases her 5.90 kg5.90 kg bowling ball with a translational speed of 2.90 m/s.2.90 m/s. At the moment of release, the ball is not rotating. As the ball slides, it begins to rotate. What is the work ?ncWnc done by friction on the ball before it transitions to rolling without slipping? Use ?=9.81 m/s2g=9.81 m/s2 for the acceleration due to gravity.

All answers were incorrect and the solutions are confusing me. Please help! Also the 4th part of the question was not answered/explained

Two identical balls, A and B, are each attached to very lightstring, and each string is wrapped around the rim of a pulley of mass Mon a frictionless axle. The only difference is that the pulley for ball Ais a solid disk, while the one for ball B is a hollow disk. If both balls are released from rest and fall the same distance,which one will have more kinetic energy, or will they have the samekinetic energy? Explain your reasoning.

Computation. Consider a frictionless flywheel in the shape of a uniform solid disk of radius 1.8 m. Calculate its mass if it takes 7.3 kJ of work to spin up the flywheel from rest to 548 rpm. [Tip: Be careful with units.] M = kg O Search Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary. Ca 4 @

A hollow sphere rolls without slipping down a ramp that is 3.5 m long. the ramp is inclined at an angle of 20˚ with the horizontal. Use the conservation of energy to find the speed of the sphere at the bottom of the slope if it starts from rest. ( I= 2/3 m R2 )

Consider a motor that exerts a constant torque of 25.0 N⋅m to a horizontal platform whose moment of inertia is 50.0 kg⋅m2. Assume that the platform is initially at rest and the torque is applied for 12.0 rotations. Neglect friction. A. How much work W does the motor do on the platform during this process? 1885 J B. What is the rotational kinetic energy of the platform Krot,f at the end of the process described above? 1885 J C. What is the angular velocity ωf of the platform at the end of this process? Enter your answer in radians per second to three significant figures.
