A 40.0-kg solid cylinder is rolling across a horizontal surface at a speed of 6.0 m/s. How much work is required to stop it?

A bowling ball of radius 8.5 cm is tossed onto a bowling lane with speed 9.0 m/s. The direction of the toss is to the left, as viewed by the observer, so the bowing ball starts to rotate counterclockwise when in contact with the floor. The coefficient of kinetic friction on the lane is 0.3. (a) What is the time required for the ball to come to the point where It is no slipping? What is the distance d to the point where the ball is rolling without slipping?

A 10.0-kg disk of radius 2.0 m rotates from rest as a result of a 20.0-N tangential forceapplied at the edge of the disk. What is the kinetic energy of thedisk 4.00 s after the force is applied?

An automobile engine can produce 200Nm of torque. Calculate the angular acceleration produced if 95.0 of this torque is applied to the drive shaft, axle, and rear wheels of a car, given the following information. The car is suspended so that the wheels can turn freely. Each wheel acts like a 15.0-kg disk that has a 0.180-m radius. The walls of each tire act like a 2.00-kg annular ring that has inside radius of 0.180 m and outside radius of 0.320 m. The tread of each tire acts like a 10.0-kg hoop of radius 0.330 m. The 14.0-kg axle acts like a rod that has a 2.00-cm radius. The 30.0-kg drive shaft acts like a rod that has a 3.20-cm radius.

A 40.0-kg solid sphere is rolling across a horizontal surface with a speed of 6.0 m/s. How much work is required to stop it? Compare results with the preceding problem.

The 10-kg wheel is subjected to a 150-N P horizontal force. The wheel starts from rest and rolls upward along the inclined plane 0= 45 degree without slipping. The radius of gyration of the wheel about its mass center O is k, = 0.3m and the radius of the wheel r=0.25 m. (a) Determine the total work done on the wheel after it has moved 2 m upward along the inclined plane. (b) Determine the angular velocity and the velocity of the wheel after it has movea 2 m upward along the inclined plane. (c) If the angle of the inclined plane is steeper (the angle is greater than 0= 45 degree), is the angular velocity of the wheel higher or lower after it has moved 2 m upward along the inclined plane? Justify your answer. P P. Figure QI Need it asap with good explanation.. thank you

8. A force of 2 N acts tangentially 30 cm from the axis of rotation of a "rolling" wheel while a force of 1.5 N acts tangentially in the opposite direction 48 cm from the axis of rotation. The wheel has a diameter 0.97 m and rolls along the ground to the right a horizontal distance of 30 m. Calculate the net work done on the wheel?

disc of radius 10cm is rotating about the central axis perpendicular to its plane. A force of 5N acts on it tangentially. The disc was initially at rest. Calculate the value of power supplied by the force when the disc has rotated by 30°.The mass of the disc is 2kg. a) 1.28W b) 1.8W c) 3.9W d) 2.63W

The 1100-kg mass of a car includes four tires, each of mass (including wheels) 35 kg and diameter 0.80 m. Assume each tire and wheel combination acts as a solid cylinder. Determine (a) the total kinetic energy of the car when travelling 95 km/h and (b) the fraction of the kinetic energy in the tires and wheels. (c) If the car is initially at rest and is then pulled by a tow truck with a force of 1500 N, what is the acceleration of the car? Ignore frictional losses. (d) What percent error would you make in part (c) if you ignored the rotational inertia of the tires and the wheels?
