Question

A space shuttle is traveling at 20,000 m/sec. At (T)ime = 5 sec, the rocket thrusters are turned on. The shuttle accelerates to 24,000 m/sec by (T)ime = 55 sec, where the thrusters are turned off. What is the shuttles average acceleration while the thrusters are on?

Answer 1

The average acceleration while the thrusters are on is 80 m/s^2.

Let:
a = acceleration = ? m/s^2
vi = initial velocity = 20,000 m/s
vf = final velocity = 24,000 m/s
t = time when shuttles were on = 50 seconds

a = (vf - vi) / t
a = (24,000 - 20,000) / 50
a = (4,000) / 50
a = 80 m/s^2
