A 1300-kg rocket has a net propulsion force of 60 kN (kiloNewtons). Over a short time period, it uniformly speeds up from an initial velocity of 35 m/s to a final velocity of 55 m/s. Assume that the mass of the rocket is constant during this time period and that the net force is along the direction of motion.

Please answer all components of question. What is the change in speed of the rocket in m/s and in mph? m/s mph Submit Answer Tries 0/2 What is the magnitude of the impulse delivered to the rocket during this time period? kg*m/s Submit Answer Tries 0/2 How long did it take for the rocket to speed up from 35 m/s to 55 m/s? Submit Answer Tries 0/2 What is the magnitude of the acceleration of the rocket? m/s2 Submit Answer Tries 0/2 What are the initial and final kinetic energies of the rocket in kilojoules (kJ)? KE initial: KE final: kJ Submit Answer Tries 0/2 What is the net work done on the rocket in kilojoules (kJ)? Submit Answer Tries 0/2 How far did the rocket travel during this time period?

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
