5. A chest of drawers weighing 240 N is at rest on a horizontal floor. The coefficients of friction are μr=0.50 and μk=0.40. If you push horizontally with a force of magnitude FP, what is the minimum value of F p that is needed to start the chest moving? A. 96 N B. 60 N C. 120 N D. 168 N E. 180 N 6. Two ice skaters, a 60 kg boy, and a 35 kg girl push off against one another starting from a stationary position. The boy pushes east with a force of 50 N for 1.75 s. What is the magnitude of the girl's final velocity? A. 1 m/s B. 0.92 m/s C. 0.83 m/s D. 2.5 m/s E. other
