A string with a mass m = 6.00 g and a length L = 5.00 m has one end attached to a wall; the other end is draped over a small, fixed pulley a distance d = 3.00 m from the wall and attached to a hanging object with a mass M = 2.00 kg as in the figure below. If the horizontal part of the string is plucked, what is the fundamental frequency of its vibration?
A wooden rod of negligible mass and length 82.2 is pivoted about a horizontal axis through its center. A white rat with mass 0.440 clings to one end of the stick, and the mouse with mass 0.220 clings to the other end. The system is released from rest..
It makes a head on elastic collision at B with a block of mass m2 = 12.0 kg that is initially at rest. Compute the maximum height to which m1 rises after the collision. height = 5m
find the ratio of vb to vr, where vr is defined above and vb is the boats speed with respect to the water.
