INSTANT ANSWER

A 30-lb block is supported by the spring shown. If the block is moved 1 inch vertically downward from its equilibrium position and released, determine (a) the period and frequency of the resulting motion, (b) velocity and acceleration of the block, in in/s and in/s, respectively after 3s.

INSTANT ANSWER

As shown in the figure, a weight of W=4 lb rests upon a frictionless surface between two springs have a constants k1=1.5 lb per in and k2=2.5 lb per in. The weight is released from rest when it is % in from its equilibrium position. Determine the period of vibration and velocity as it passes through the equilibrium position.

INSTANT ANSWER

A 200 lb man floats on a 6 ft by 2 ft inflatable raft in a quiescent swimming pool. Estimate the period of vertical bobbing of the man and raft system should the man be disturbed. Assume that the weight of the man is distributed uniformly over the raft and that the mass of the raft is negligible.
