A 10-kg block is attached to spring A and connected to spring B bycord and pulley. The block is held in the position shown(block is held above ground on support with spring under supportand on top of pulley, both with k=2 kN/m) with both springsunstretched when the support is removed and the block is releasedwith no initial velocity. Knowing that the constant of eachspring is 2 kN/m, determine (a) the velocity of the block after ithas moved down 50 mm, (b) the maximum velocity achieved by theblock.
it takes 0.5 seconds for one to lift the cart handle from 0 to 450 in a linear way around o. if the block has a mass of
the 10 pounds weight is supported by the cord AC and roller and by a spring.if the spring has unstreched lenngth of 8 inches and the weight in equilibrium when d=a inches.determine the stiffness K of the spring?
