The figure shows a box of mass m = 4.65 kg pulled to the right across a horizontal surface by a constant tension force of magnitude T = 23.0 N. The tension force is inclined at an angle θ = 21.5∘ above the horizontal and the friction force has magnitude fk = 13.0 N. The box is pulled a distance d = 2.15 m. Determine the work done on the box by the tension force, the normal force, and the kinetic friction force. We'll use WT, Wn, and Wfk to represent the magnitudes of the tension, normal, and friction forces, respectively. WT = J Wn = J wfk =

An initially stationary block of mass m = 5.0 kg is attached to a relaxed spring with a spring constant K = 16 N/m on a rough plane inclined at an angle θ (with cos⁡θ = 0.8 and sin⁡θ = 0.6). The coefficient of kinetic friction between the block and the plane is μk = 0.40. A vertically downward uniform force F = 240 N acts on the block as it moves from A to B a distance d = 2.5 m down the plane. During this descent from A to B , calculate the amount of work done on the block by: a) the normal force, b) the gravitational force, c) the spring force, d) the force F , and e ) the force of kinetic friction. f) Deduce the kinetic energy and the speed of m as it passes through point B.
