Physics

A 1300-kg rocket has a net propulsion force of60 kN (kiloNewtons). Over a short time period, ituniformly speeds up from an initial velocity of 40m/s to a final velocity of 55 m/s. Assumethat the mass of the rocket is constant during this time period andthat the net force is along the direction of motion.

A) What is the change in speed of the rocket inm/s and in mph?
m/s
mph

Tries 0/2


B) What is the magnitude of theimpulse delivered to the rocket during this timeperiod?
kg*m/s

Tries 0/2


c) How long did it take for the rocket to speed upfrom 40 m/s to 55 m/s?
s

Tries 0/2


D) What is the magnitude of theacceleration of the rocket?
m/s2

Tries 0/2

E) What are the initial and final kineticenergies of the rocket in kilojoules (kJ)?
KE initial:  kJ
KE final:  kJ

Tries 0/2


F) What is the net work done on the rocket inkilojoules (kJ)?
kJ

Tries 0/2


G) How far did the rocket travel during this timeperiod?
