- A 7920 kg space probe, moving nose-first toward Jupiter at 108 m/s relative to the Sun, fires its rocket engine, ejecting 85.0 kg of exhaust at a speed of 255 m/s relative to the space probe. What is the final velocity of the probe?A 3.7-kg model rocket is launched, shooting 58.6 g of burned fuel from its exhaust at an average speed of 604 m/s. What is the speed of the rocket after the fuel has burned (ignore gravity and air resistance). Answer: + m/sAn astronaut of mass 180 kgkg including his suit and jet pack (when the jet pack is FULL and no gas has been used yet) wants to acquire a velocity of 1.6 m/sm/s to move back toward his space shuttle.Assuming the jet pack can eject gas with a velocity of 60 m/sm/s , what mass of gas will need to be ejected?
- What is the magnitude of the momentum of a 0.22 kg ball traveling at 34 m/s?You put an antimatter explosive in a 133 kg space rock, initially moving to the right at 34 m/s. This time, upon detonation, the rock fractures into three pieces. A 16 kg chunk is observed to zip off to the right (the positive direction) at 60 m/s. A 69 kg chunk is observed to zip off to the left at 59 m/s. Calculate the final velocity of the third chunk, in m/s. (Please answer to the fourth decimal place - i.e 14.3225)Look at the picture
