(10%) Problem 10: A rocket accelerates upward from rest, due to the first stage, with a constant acceleration of a1 = 78 m/s for 1 = 24 s. The first stage then detaches and the second acceleration two stage fires, providing a constant acceleration of a2 = 25 m/s-for the time interval 12 = 62 s. a acceleration one Otheexpertta.com A 33% Part (a) Enter an expression for the rocket's speed, v1, at time t1 in terms of the variables provided.
