1. [-/6 Points] DETAILS MY NOTES SERCP11 5.1.OP.006. 0/5 Submissions Used ASK YOUR TEACHER A box with a mass of 42.5 kg is pushed with a horizontal force of 150 N. The box moves at a constant speed across a level, rough plane a distance of 6.80 m. (a) What is the work done (in ]) by the 150 N force? (b) What is the coefficient of kinetic friction between the box and the plane? Need Help? Read It Submit Answer2. [-/8 Points] DETAILS MY NOTES SERCP11 5.1.P.008. 0/5 Submissions Used ASK YOUR TEACHER A block of mass m = 2.50 kg is pushed d = 2.90 m along a frictionless horizontal table by a constant applied force of magnitude F = 12.0 N directed at an angle 8 = 25.0 below the horizontal as shown in the figure below. s (a) Determine the work done by the applied force. L (b) Determine the work done by the normal force exerted by the table. (c) Determine the work done by the force of gravity. (d) Determine the work done by the net force on the block.
