Question

A space ship is traveling at 20,000.0 m/s. After 5.0 seconds, the rocket thrusters are turned on. At the 55.0-second mark, the ship has a velocity of 24,000.0 m/s. What is the acceleration?

Answer 1

Step-by-step explanation:

Use the kinematic equation v₂ = v₁ +at

Final velocity is equal to the initial velocity plus the acceleration times time.

24,000 = 20,000 + 55a

4,000 = 55a

a = 72.7 m/s²
