An astronaut of mass 60 kg and a small asteroid of mass 40 are initially at rest with respect to the space station. The astronaut pushes the asteroid with a constant force of magnitude 250N for 0.35s. Gravitational forces are negligible. A)How far apart are the astronaut and asteroid 5.00s after the astronaut stops pushing? B) What is their relative speed at this time?

2. Relevant equations

TotalForcex=ma

Delta x=(1/2)(delta v)(delta t)

Delta v=a(delta t)

3. The attempt at a solution

1. Total force of x is 250N, so 250N=ma=250N/40= acceleration = 6.25m/s^2

2. (deltax)=(1/2)(6.25)(5.35)^2 = 89.4

3. Vf=(6.25)(5.35)=33.4 m/s

Does this look alright?
