A bulldozer drags a 252 kg long along the rough horizontal ground. The cable attached to the log applies a 525 N force at an angle of 30.0 degrees above the ground. The coefficient of kinetic friction between the log and the ground is 0.150. Assume the direction of motion is +x and upwards is +y.  What is the normal force acting on the log?   What kinetic friction force is acting on the log? (With proper sign)  What is the acceleration of the log?

The second force has a magnitude of 0.600 N0.600 N and points 75.075.0° north of east. If these are the only two forces acting on the puck, what will be the magnitude and direction of the puck's acceleration? Enter the direction as an angle measured in degrees counterclockwise from due east.
