Solve Prob. 13.26, assuming that the 2-kg block is attached to the spring.Reference to Problem 13.26:A 3-kg block rests on top of a 2-kg block supported by, but not attached to, a spring of constant 40 N/m. The upper block is suddenly removed. Determine (a) the maximum speed reached by the 2-kg block, (b) the maximum height reached by the 2-kg block.
Problem 1
In the system of blocks below, the angle of friction on all surfaces of blocks A and B are 30°. The weights of blocks A and B are 1000 N and 100 N, respectively. Determine the required weight of block C so that block A is in an impending motion upward.
A 5-kg collar A is at rest on top of, but not attached to, a spring with stiffness k1 = 400 N/m when a constant 150-N force is applied to the cable. Knowing A has a speed of 1 m/s when the upper spring is compressed 75 mm, determine the spring stiffness k2 . Ignore friction and the mass of the pulley.
