While standing on a frictionless ice surface, a 50 kg skater pushes against a wall with an average force of 150 N west for 0.210 s. Calculate the velocity of the skater at 0.210 s.

This was what i did:
m = 50 kg
Fnet = 150 N
t = 0.210 s
Vf =?

Fnet = ma
Fnet/m = a
150 N/50 kg = 3 m/s^2

a = Vf-Vo/t
at - Vo = Vf
3m/s^2/0.210 s = 0.63 m/s west
