Q1 a) A child pulls and accelerates a 20 kg box along a straight path on a horizontal surface. He exerts a force of 55 N on the box at an angle of 20° above the horizontal, as shown in the figure. The coefficient of friction between the box and the surface is 0.22. 55 N 20 kg 20° Figure QA1 i i) Draw and label a free-body diagram for the box.
