A solid, horizontal cylinder of mass 8.0 kg and radius 1.30 m rotates with an angular speed of 6.50 rad/s about a fixed vertical axis through its center. A 0.250-kg piece of putty is dropped vertically onto the cylinder at a point 0.900 m from the center of rotation and sticks to the cylinder. Determine the final angular speed of the system. rad/s
Estimate the force P to accelerate the 80 - Ib block at 6ft/sec2 to the right.
A 45.5-cm diameter disk rotates with a constant angular acceleration of 2.90 rad/s2. Find the linear velocity and tangential acceleration of P at t = 2.30 s
