okay well thanks guys the rest should be right then.

I think i got it now. But one more question, so is that always how you would change the Newtons into a mass in kg by dividing it by the acceleration due to gravity or is there a formula to manipulate.

i know but the problem has given me a weight of the astronaut and his equipment in Newtons not in kg so how can i solve for the acceleration

Homework Statement On the earth, an astronaut and the equipment weigh 1,960 N. Weightless in space, the motionless astronaut and equipment are accelerated by rocket pack with 100 N thrust, that fires for 2.0s. What is the resulting final velocity? (Hint: First calculate the acceleration...

Alright thanks I thought that was the correct formula, what i was not sure about was the units thanks.

A 15 g bullet is fired is fired with a velocity of 220 m/s from a 6.5 kg rifle. What is the recoil velocity of the rifle? That is the problem I think i use the formula... This half of the equation equals zero due to the initial velocity equaling zero = Mass of the gun*Velocity of the...
