Use the worked example above to help you solve this problem. A rocket has a total mass of 1.04 x 105 kg and a burnout mass of 1.07 x 104 kg, including engines, shell and payload. The rocket blasts off from Earth and exhausts all its fuel in 3.86 min, burning the fuel at a steady rate with an exhaust velocity of v = 4.16 x 10³ m/s. (a) If air friction and gravity are neglected, what is the speed of the rocket at burnout? m/s (b) What thrust does the engine develop at liftoff? N (c) What is the initial acceleration of the rocket if gravity is not neglected? m/s² (d) Estimate the speed at burnout if gravity isn't neglected. m/s
