Q. Imagine a frictionless pulley (a solid cylinder) of unknown mass M and radius r = 0.200 m which is used to draw water from a well. A bucket of mass m = 1.50 kg is attached to a massless cord wrapped around pulley. The bucket starts from rest at the top of the well and falls for t = 3.00 s before hitting the water h = 5.58 m below the top of well.
A 2m long pendulum with a mass of 250gr collides with a 95gr sticky ball seating in the pendulum's path and at the edge of a horizontal surface. The collision takes place while the pendulum is passing by its lowest point.
