A box of mass 30 kg is pushed horizontally across the floor with a force to the left of 210 N and to the right with a force of 50 N. The coefficient of friction is 0.2. a) Draw a FBD of the box. Indicate x- and y axes of your choice.

b) Determine the weight of the box. c) Determine the size of the normal force. d) Determine the size of the frictional force. e) Find the resulting acceleration of the box
