A 63 kg astronaut drifting with 7.0 m/s to the right with

respect to a spacecraft uses a jetpack to slow down.

Suppose it takes 14.0 s to come to a stop with respect to the spacecraft. What is the force exerted by the jetpack?

31.5N

Explanation:

M = 63kg, v = 7.0m/s t = 14.0s F = ?

Force = Mass * acceleration

but acceleration = change in velocity / time

a = dV/dt

F = (63 * 7.0) / 14

F = 31.5N
