A record of mass m and radius r sits on a frictionless turntable. you apply torque in the record causing it to undergo a constant angular acceleration.You now put a different record in the turntable and apply the same torque, but the angular acceleration is now twice as large. Which of the following could be the mass and radius of the new record?
a) m and 2r
B) m and r/2
C) 2m and 2r
D) 2m and r/2
E)2m and r

A turntable has a radius R and mass M (considered as a disk) and is rotating at an angular velocity W 0 about a frictionless vertical axis. A piece of clay is tossed onto the turntable and sticks d from the rotational axis. The clay hits with horizontal vel ocity component vc at right angle to the turntable’s radius, and in a direction that opposes the rotation. After the clay lands, the turntable has slowed to angular velocity W1 ....

A solid sphere of mass M and radius R sits on a an incline of angle θ, when it is let go it rolls down-hill without slipping at total vertical distance of h. At the bottom of the hill the ball moves onto a horizontal surface and enters into a completely elastic collision with a stationary block of height 2R and mass 2M. Find the speed of the block right after the collision.

Consider a cylindrical turntable whose mass is M and radius is R, turning with an initial angular speed ω1. (a) A parakeet of mass m, after hovering in flight above the outer edge of the turntable, gently lands on it and stays in one place on it, as shown below. What is the angular speed of the turntable after the parakeet lands? (Use any variable or symbol stated above as necessary.) ωf = (b) Becoming dizzy, the parakeet jumps off...

A uniform cylindrical turntable of radius 1.80 m and mass 26.0 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4π rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.49 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.70 m to the east of the axis. (a) Find the final angular speed of the clay...

Please answer ALL parts.
A phonograph turntable driven by an electric motor accelerates at a constant rate (i.e., constant angular acceleration) from 0 to 33.33 revolutions per minute in 2 minutes. The turntable is a uniform disc of mass 1.5 kg and radius R = 13 cm, as indicated in the figure. The radius of the driving wheel is r = 2.0 cm. What is the torque required to drive the turntable at this angular acceleration? If the driving wheel...

Consider a bicycle wheel of mass M and radius R that sits on a flat, level surface, such that the surface is tangent to the wheel. One end of a spring (spring constant, k) is attached to bicycle wheel’s hub, and the other end is fixed to a vertical wall. The spring is horizontal. There is sufficient friction to prevent the wheel from sliding at the point of contact with the surface. When the center of the wheel is directly...
