A spring with spring constant 33 N/m is attached to the ceiling, and a 4.5 cm diameter, 1.5 kg metal cylinder is attached to its lower end. The cylinder is held so that the spring is neither stretched nor compressed, then a tank of water is placed underneath with the surface of the water just touching the bottom of the cylinder. When released, the cylinder will oscillate a few times but, damped by the water, quickly reach an equilibrium position. When in equilibrium, what length of the cylinder is submerged?
You pull downward with a force of 32 N} on a rope that passes over a disk-shaped pulley of mass 1.2 kg and radius 0.07 5m. Find the linear acceleration of the 0.61 kg mass.
The height of a helicopter above the ground is given by h = 2.95t^3, where h is in meters and t is in seconds. At t = 2.50 s, the helicopter releases a small mailbag.
