A rectangular box of mass 7 kg rests on a table. A force of 30 N is applied to the box in a direction making an angle of 33 with the horizontal as shown in the figure. a) Draw a free-body diagram showing all the forces (including friction) acting on the box. b) What is the acceleration of the box if there is no friction? c) If we have a friction force of 13.2 N acting on the box, what would the acceleration of the box be?
