[SOLVED] Momentum. resulting velocity. Rocket
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?
I have to be missing something. I tried using every formula given to me in class and I cannot get anywhere. Please help. Thanks.
p=mv
Ft= (mf)(vf)-(mi)(vi)
Ft=ma+v(difference of m/t)
m1v1=m2v2
I tried a few and can't get a relevant answer. I really do not know where to begin with the rocket.
