A uniform string of length l and mass m hangs by one end from the ceiling. (a) Prove the speed of sound in the string a distance y above the bottom is vs = √gy, where g is the acceleration due to gravity. Hint: The tension in the string is due to string’s mass under the influence of gravity, and that tension increases as you go higher up the string. (b) You quickly and gently hit the bottom of the...

A wooden plank of length L and mass M is hanging vertically attached to the ceiling by a frictionless hinge. The plank is in equilibrium, when struck by a bullet of mass m that has velocity given by the equation below. The bullet hits the plank at a distance D (D< L) from the ceiling and remains stuck in the plank. ~v = vxˆi + vyˆj -> velocity of the bullet. a) What is the angular acceleration of the plank...

A rod with length L and mass M hangs vertically on a frictionless, horizontal axel passing through its center. A ball of mass m traveling horizontally at speed v0 hits and sticks to the very bottom tip of the rod. To what maximum angle, measured from vertical, does the rod, with the attached ball, rotate? Answer in terms m, M, v0, L, and g.
