A rocket ship is moving through space at 1200 m/s. The rocket ship accelerates at a rate of 4 m/s in the same direction. What is the rocket ship's speed after 200 seconds of acceleration?

Answer:

Vf = 2000 [m/s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} =v_{o}+a*t\\[/tex]

where:

Vf = final velocity [m/s]

Vo = initial velocity = 1200 [m/s]

a = acceleration = 4 [m/s]

t = 200 [s]

Vf = 1200 + (4*200)

Vf = 1200 + 800

Vf = 2000 [m/s]
