An unknown body with radius R=30 cm and Inertien M=2.0 kg Rolls across the floor. We can measure the inertial moment of a body around the Ashes passing through the centre of
I=0.12 kg m2/s2
What kind of body are we talking about?
- A solid bullet?
- A solid cylinder?
- A hollow cylinder?
- In Kugleskal?

A hollow sphere of mass 0.22 kg and radius 0.03 m is rolling across the floor at velocity of 3.8 m/s. It then encounters an incline of θ = 16° when it starts to slow down as it rolls up the ramp. What is the initial angular velocity of the hollow sphere before it starts to decelerate? Considering up the ramp to be the positive direction, what is the magnitude of the linear and angular deceleration as the hollow sphere...

A hollow sphere of mass m = 0.35 kg and radius r = 64 cm rolls along a flat surface at an initial speed of v, and then up a curved ramp with radius of curvature 4.7 m without slipping, until it reaches a maximum angle of 12 degrees around the curve and starts to roll backward. What was the initial speed of the ball in units of meters/second?

A thin hoop of radius r = 0.82 m and mass M = 7.3 kg rolls without slipping across a horizontal floor with a velocity v = 1.1 m/s. It then rolls up an incline with an angle of inclination theta = 44 degrees. a) What is the maximum height h reached by the hoop before rolling back down the incline? b) Now, suppose a uniform solid sphere is used instead of a hoop. Use the same values of r,...

A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°
A solid cylinder of radius 10 cm and mass 13 kg starts from rest and rolls without slipping a distance of 6.0 m down a house roof that is inclined at 30°. (See the figure.) What is the angular speed of the cylinder about its center as it leaves the house roof? The outside wall of the house is 5 m high. How far from the edge of the roof does the cylinder hit the level ground?
