Question

A rocket sled of mass M is to be decelerated by a scoop, a sin Fig. P3.108, which has width b into the paper and dips into the water a

depth h, creating an upward jet at 60°. The rocket thrust is T to the left. Let the initial velocity be Vo.and neglect air drag and wheel friction. Find an expression for Vir) of the sled for (a) T = 0 and (b) finite T 0.
