Buster Rockets and a Spaceship

CLMECH-RMVO3X

A 3,200-kg spaceship is moving at a constant velocity far from any celestial objects. A small rocket with a constant thrust of 5.8 N is fired to change the spaceship's speed.

By how much does the speed of the spaceship change if the rocket is fired for 2.8 minutes in the direction opposite from the spaceship's original motion? Assume that the mass of the spaceship does not change.

A

$0.30 \space \frac{m}{s}$

B

$0.64 \space \frac{m}{s}$

C

$0.21 \space \frac{m}{s}$

D

$0.98 \space \frac{m}{s}$
