The upward velocity of a rocket can be computed by the following formula: v = u In m 0 m 0 − q t − g t where v = upward velocity, u = the velocity at which fuel is expelled relative to the rocket, m 0 = the initial mass of the rocket at time t = 0 , q = the fuel consumption rate, and g = the downward acceleration of gravity ( assumed constant = 9.81 m / s 2 ) . IF u = 2200 m / s, m 0 = 160 , 000 kg, and q = 2680 kg / s , compute the time at which v = 1000 m / s . (Hint: t is somewhere between 10 and 50 s.) Determine your result so that it is within 1% of the true value. Check your answer.
