Question

Problem i: A rocket accelerates upward from rest, due to the first stage, with a constant acceleration of a 73 s for 35 s. The first stage then detaches and the second stage fires, providing a constant acceleration of a2 41 m/s for acceleration two the time interval t2 52 s. acceleration one Part (a) Enter an expression for the rocket's speed, v1, at time t1 in terms of the variables provided Expression Select from the variables below to write your expression. Note that all variables may not be required. cu, B, e, a a2, d, g, h, i, j, m, P. t, tl, t Otheexpertta.com

Explanation / Answer

v1 = u1 + a1t1 = a1t1.......at the end of t1

v2 = v1 + a2(t2 - t1) = a1t1 + a2(t2 - t1) .......at the end of t2
