A 500kg spacecraft was traveling through space at a constant velocity when it fired its rocket engine. The engines produce a 1000N of thrust. The spacecraft was traveling at 400 m/s after 100 seconds.

Question

A 500kg spacecraft was traveling through space at a constant velocity when it fired its rocket engine. The engines produce a 1000N of thrust. The spacecraft was traveling at 400 m/s after 100 seconds.  
What is the rate of acceleration for the space craft?

Mathematicians · Accepted Answer

A = F÷M F= 1000N M= 500kg 1000÷500= 2. So 2m/s^2

oobleck · Answer

again? F = ma 1000 = 500a a = 2 m/s^2
