Two rockets are launched at a fireworks performance. Rocket A is launched with an initial velocity v0 and rocket B is launched 4 s later with the same initial velocity. The two rockets are timed to explode simultaneously at a height of 240 ft, as A is falling and B is rising. Assuming a constant acceleration g = 32.2 ft/s2 determine(a) The initial velocity v0,(b) The velocity of B relative to A at the time of theexplosion.
