I guess net force includes gravity down so
Force * time = change of momentum
6000 * 2.5 = 2000 (v-10)
When a rocket is 3km above the ground,it has an upward velocity of 10 m.s^-1.A booster rockect is fired downward,resulting in a net force of 6000 N being exerted upward on the shuttle.The time it takes the booster to leave the shuttle after being fired is 2,5 seconds.if the mass of the shuttle is 2000 kg,
calculate the velocity of the shuttle immediately afta the booster is fired
