A solid, uniform disk of radius 0.250 m and mass 55.9 kg rolls down a ramp of length 4.90 m that makes an angle of 14.0° with the horizontal. The disk starts from rest from the top of the ramp. (a) Find the speed of the disk's center of mass when it reaches the bottom of the ramp. m/s (b) Find the angular speed of the disk at the bottom of the ramp. rad/s

A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 8.09 m/s at the bottom of the rise. Find the translational speed at the top. Number i Units 0.760 m

A uniform solid 5.25-kg cylinder is moving up a ramp that is incline at 30° to the horizontal. The initial speed of the cylinder at the bottom of the ramp is 5.00 m/s. Find the maximum distance, d, the cylinder rolls up the ramp (this is not the final height but the length of the incline that the cylinder travels). The moment of Inertia of the cylinder is I = ½ MR².

A solid, uniform disk of radius 0.250 m and mass 57.8 kg rolls down a ramp of length 4.70 m that makes an angle of 16.0° with the horizontal. The disk starts from rest from the top of the ramp.

In figure given below, a constant horizontal force Fapp of magnitude 19 N is applied to a uniform solid cylinder by fishing line wrapped around the cylinder. The mass of the cylinder is 6 kg, its radius is 0.20 m, and the cylinder rolls smoothly on the horizontal surface. What is the magnitude of the acceleration of the center of mass of the cylinder? (Your answer must be in units of m /s2 and include 2 digit after the decimal point. Maximum of 5% of error is accepted in your answer.) (Hint: Icom = MR²) Fapp -Fishing line

9 of 24 Constan A machinist turns the power on to a grinding wheel, which is at rest at time t=0.00 s. The wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 25 rad/s. The wheel is run at that angular velocity for 37 s and then power is shut off. The wheel decelerates uniformly at 1.5 rad/s² until the wheel stops. In this situation, the time interval of angular deceleration (slowing down) is closest to: Part A O 17 s 23 s 15s 19 s 21 s 0000 Submit Request Answer Provide Feedback Next>

Consider the father pushing a playground merry-go-round. He exerts a force of 250 N at the edge of the 50.0-kg merry-go-round, which has a 1.50-m radius. Calculate the angular acceleration produced (a) when no one is on the merry-go-round and (b) when an 18.0-kg child sits 1.25 m away from the center. Consider the merry-go- round itself to be a uniform disk with negligible friction.
