Asked by Chris
A rocket of mass 1.0x10^3kg is being fired to a height of 5.0 x 10^3 m. The rocket engine shuts off when the rocket reaches a height of 1.0x10^3m, and the rocket coasts up to 5.0 x 10^3 m.
A) What velocity must the rocket have at the 1.0x10^3 m point to enable it to reach 5.0 x 10^3m
B) What acceleration did the rocket experience while the engine was on? off?
C) What force did the rocket engine exert on the rocket?
