Friction
A 200kg crate us pushed horizontally with a force of 700 N. If the coefficient of friction is 0.20, calculate the acceleratio of the crate. I tried doing this but I don't seem to be getting the right answer. m = 200 kg f(app)= 700 N U = 0.20 Ff = (0.20)(200)(-9.81) =-392.4 N ...

You should add forces to get net force netforce=fapplied+friction and then fricion force is a negative, so netforce=700-392.4
