What is the angular momentum of a 0.190 kg ball rotating on the end of a thin string in a circle of radius 1.00 m at an angular speed of 10.1 rad/s ? Express your answer using three significant figures and include the appropriate units.
1. What is the angular momentum of a 0.240-kg ball rotating on the end of a thin string in a circle of radius 1.35 m at an angular speed of 15.0 rad/s ? 2. A diver can reduce her moment of inertia by a factor of about 4.0 when changing from the straight position to the tuck position. If she makes 2.0 rotations in 1.5 s when in the tuck position, what is her angular speed (rev/s) when in the...
What is the magnitude of the angular momentum of a 1.0-g particle moving counterclockwise (as viewed from above) with an angular speed of 5 pi rad/s in a horizontal circle of radius 16 cm ? Express your answer using two significant figures. L = kg middot m^2/s What is the direction of the angular momentum upward downward
A 3 kg disk of radius 0.25m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center of mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft(the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia of the shaft is negligible, a) What is the angular speed of the disk-ball combination, b)...
