thank you! i got it!

Homework Statement a box of mass 5.0 kg is accelerated from rest across a floor at a rate of 2.0m/s^2 for 7.0s. find the net work done on the box. Homework Equations f = ma w= fdcostheta The Attempt at a Solution f = ma f=10 w = fdcostheta w=10d w=10*v*t w=10*v*7...

okay so after that i get: netfx=m1a Fa-19.6sin60=m1a netfy=m1a fn-19.6cos60=0 Fn=19.6cos60 and I am stuck again, is this right so far?
