A rocket engine uses fuel and oxidizer in a reaction that produces gas particles having a velocity of 1380 ms-1

. The desired thrust is to be 195000 N.
16. What must be the fuel/oxidizer consumption rate (in kg s-1
)?
16.
17. If the initial weight of the rocket is 125000 N, what is its initial acceleration?
17.
18. What are the weight and acceleration of the rocket at t = 15.0 s after
ignition? 18.

19. What are the weight and acceleration of the rocket at t = 20.0 s after ignition?
