Chapter 6, Problem 78EP
A spacecraft cruising in space at a constant velocity of 2000 ft/s has a mass of 25.000 Ibm. To slow down the spacecraft. a solid fuel rocket is fired, and the combustion gases leave the rocket at a constant rate of 150 Ibm/s at a velocity of 5000 Iii in the same direction as the spacecraft for a period of 5000 ft/s. Assuming the mass of the spacecraft remains constant, determine (a) tire deceleration of the spacecraft during this 5-s period. (b) the change of velocity of the spacecraft during this time period, and (c) the thrust exerited on the spacecraft.

surface. The block Is originally revolving at a distance of 0.40 m from the hole witha speed of 0.70m/s. The
cord Is then pulled from below, shortening the radlus of the circle in which the block revolves to 0.10 m. At
