A rocket rises vertically from rest with an acceleration, Ask an Expert

Academics

A rocket rises vertically, from rest, with an acceleration of3.2 m/s2 until it runs outof fuel at an altitude of 1000 m. After this point, its acceleration is that of gravity, downward.

(a) What is the velocity of the rocket when it runs out of fuel?(Assume up is positive.)

m/s

(b) How long does it take to reach this point?

(d) How much time (total) does it take to reach maximumaltitude?

(e) With what velocity does the rocket strike the Earth? (Assume upis positive.)

m/s

(f) How long (total) is it in the air?
