Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. Block D, initially at rest, having a W = 30 lbf , is supported within the system shown, with x = 13.2 ft. Neglecting the mass of the pulley and the cord on the system, determine the eventual height h after a force P = 60 lbf is applied to make the block rise by ∆sD = 0.625 ft at t = 2.5 s. NOTE: Use Force-Mass-Acceleration (FMA) Method.

. To promote their new album, Black Pink decided to launch a satellite into orbit that will intercept all airwaves and play their songs worldwide. To do this, he needs to mount a 200 [kg] satellite onto an 850 [kg] rocket. It blasts off vertically from a launchpad with a constant net upward acceleration of 3.80 [m/s2]. When it has reached a height of 680 [m], the satellite was released, and the rocket blew up shortly after, due to a system failure. Assume that the satellite was not damaged after the explosion. (a) What is the maximum height that the satellite will reach above the launchpad? (b) How much time will elapse after system failure before the satellite comes crashing down the launch pad? (c) How fast will the satellite be moving just before it crashes?
