Question

79) Between t = 0 and t = t0, a rocket moves straight upward with an acceleration given by a(t)=A−Bt1/2a(t)=A−Bt1/2, where A and B are constants. (a) If x is in meters and t is in seconds, what are the units of A and B? (b) If the rocket starts from rest, how does the velocity vary between t = 0 and t = t0? (c) If its initial position is zero, what is the rocket’s position as a function of time during this same time interval?
