A constant torque of 25.0 N ? m is applied to a grindstonewhose moment of inertia is 0.130 kg ? m2. Using energy principlesand neglecting friction, find the angular speed afterthe grindstone has made 15.0 revolutions. Hint: The angular equivalent of Wnet =FΔx = 1/2 mvf 2- 1/2 mvi 2 is Wnet =τ Δ θ =1/2 Iωi2 - 1/2 Iωi2. You should convince yourself that this last relationshipis correct.
A 2.40-kg cylindrical rod of length 2.00 m is suspended from a horizontal bar so it is free to swing about that end. A solid sphere of mass 0.25 kg is thrown horizontally with a speed v, = 13.5 m/s to hit the rod at the point A one-fifth of the way up from the bottom of the rod. The sphere bounces back horizontally with a speed v, = 9.50 m/s, while the rod swings to the right through an angle 0 before swinging back toward its original position. What is the angular speed of the rod immediately after the collision? rad/s (a) (b)
a rigid assembly of a thin hoop (of mass mand radius R = 0.150 m) and a thin radial rod (of mass m and length L = 2.00R). The assembly is upright, but if we give it a slight nudge, it will rotate around a horizontal axis in the plane of the rod and hoop, through the lower end of the rod. Assuming that the energy given to the assembly in such a nudge is negligible, what would be the assembly’s angular speed about the rotation axis when it passes through the upside-down (inverted) orientation?
