Question

A box with mass 4.8 kg initially at rest is pushed by applying a force of 11.5 N on a rough surface with coefficient of friction $mu$ = 0.4. Assume the box is displaced a distance 1.4 m. The applied force is at angle 23.7$^{circ}$ as shown in the diagram. The acceleration due to gravity is $g$ = 10m. s$^{-2}$. Use the work energy theorem to find the speed of the box when it is displaced a distance 1.4 m. (Answers with two decimal places, do not include unit in your final answer)
