The second stage of the two-stage rocket weighs 2900 lb (empty) and is launched from the first stage with a velocity of
3000m(i)/(h). The fuel in the second stage weighs 1000 lb . It is consumed at the rate of
50l(b)/(s)and ejected with a relative velocity of
6500f(t)/(s). Neglect the effect of gravitation. Part A Determine the acceleration of the second stage just after the engine is fired. Express your answer to three significant figures and include the appropriate units.
a=Part B What is the rocket's acceleration just before all the fuel is consumed? Express your answer to three significant figures and include the appropriate units.
a=
