1. Two rockets are launched. The initial velocity of rocket A is vo = 98m/s and rocket B is launched t, seconds later after A with the same initial velocity. The two rockets are timed to explode simultaneously at a height of 298m as A is falling B is rising. Assuming a constant acceleration g = 9.81m/s² , determine (a) the time t, , (b) the velocity of B at the time of explosion.
