difference of momentum= (100N)(2.0s) = 200kgm/s
200kgm/s= (1960N/ 9.8m/s^2) V
V=1m/s
I first found the difference of momentum which is force * time. then used the equation momentum=mass*velocity. Is this correct?
[SOLVED] Momentum. resulting velocity. Rocket
Homework Statement
On earth, an astronaut and equipment weigh 1,960.0 N. While weightless in space, the astronaut fires a 100 N rocket backpack for 2.0 s. What is the resulting velocity of the astronaut and equipment?
