help with a physics problem?

A 202-kg crate is pushed horizontally with a force of 709 N. If the coefficient of friction is 0.20, what is the acceleration of the crate?

Net force equals mass time acceleration
The net force is 709 minus friction

friction is
202*9.8*0.20
therefore
709-202*9.8*0.20=202*a
solve for a
a=1.55 m/s^2
