Suppose that the missile shown at the right lifts off at t = 0 from the ground and, because it becomes lighter as its fuel is expended, its acceleration (in g's) is given as a function of time in seconds by: ag(t) a B-yt' where a, , and y are positive constants. a) What is the missile's velocity v(t) miles per hour after liftoff? b) How much distance in feet the missile has travelled in time t? B-yt c) Repeat (a) and (b) if ag(t) = = Suppose that the missile shown at the right lifts off at t = 0 from the ground and, because it becomes lighter as its fuel is expended, its acceleration (in g's) is given as a function of time in seconds by: ag(t) a B-yt' where a, , and y are positive constants. a) What is the missile's velocity v(t) miles per hour after liftoff? b) How much distance in feet the missile has travelled in time t?
