A metal cup of mass M = 590 g hangs on a light rod. There is an shaft at the end of the rod that allows the rod to rotate freely and smoothly around the shaft. Rod length is = 1.1 m. The Baseball pitcher throws the ball (mass m = 147 g) exactly into the cup where it will remain.
Determine the speed vmax at which the ball should come into the cup to rotate it all the way around its axis. The ball does not fall from the cup.
Homework Answers
Here minimum kinatic energy should be such that, the combined system of cup and ball should reach the top of circular path that it will trace. Hence whole kinatic energy should be equal to change in potential energy between bottom and top position

Christian throws the ball at a speed of 88 km / h vertically in
a hanging bag, where it also stays. The mass M of the empty bag can
be changed by adding a suitable amount of lead pellets there.
a) The bag hangs on a light and unstretchable string, the top of
the string is attached to a branch around which the string can
rotate. Length of string l = 1.6. Determine what the bag's mass

AXis Two spheres of mass m are attached to a light rod of length 2L. The rod is fixed at its center to a freely-rotating axis. The rod is horizontal when a small bird of mass 5m carefully lands on the right sphere. Express a answers in terms of m, L, and g (a) What is the net torque on the system the instant the bird lands (while the rod is still horizontal)? (b) Determine the angular acceleration of the...

An object of mass m 214 g hangs by a light string wrapped around a light inner pulley (hub) having radius R, - 18.7 em. This inner pulley is the hub of a circular wheel having radius R2 = 24.9 cm and mass Mwheel 768 g. Assume the entire wheel assembly rotates without friction and that the inner polley has negligible mass. What is the tangential speed of a point on the rim of the inner pulley at time t...
