Ohh I see the pulling force is 220.5 The frictional force is 66 For the normal force I actually got 367.85 I just don't understand how you solved for acceleration by saying 1/2-1/5*7.96

physics
Sorry I meant 47 kg.

physics
For the frictional force I got 61.4 For the magnitude of the Normal force I got -398.5 and for the amount of force pulling you down the slope I got -250.2 I don't think that's right though.

physics
Oh sorry. To find the frictional force is it (0.18)*(47.0)(9.80)cos37 degrees and the magnitude of the Normal force is (47.0)(9.80)cos37 degrees

physics
Is this right? (45.0)*(9.80)*(sin35 degrees)= a number a number - frictional force = answer
