A 5.0-kg box slides a 10-m distance on ice. If the coefficient of kinetic friction is 0.20, what is the work done by the friction force?
Answer to relevant QuestionsIf a 10-N force is used to compress a spring with a spring constant of 4.0 x 102 N/m, what is the resulting spring compression? A particular spring has a force constant of 2.5 x 103 N/m. (a) How much work is done in stretching the relaxed spring by 6.0 cm? (b) How much more work is done in stretching the spring an additional 2.0 cm? A 2.00-kg mass is attached to a vertical spring with a spring constant of 250 N/m. A student pushes on the mass vertically upward with her hand while slowly lowering it to its equilibrium position. (a) How many forces do ...A 3.00-kg block slides down a frictionless plane inclined to the horizontal. If the length of the plane’s surface is 1.50 m, how much work is done, and by what force? A girl swings back and forth on a swing with ropes that are 4.00 m long. The maximum height she reaches is 2.00 m above the ground. At the lowest point of the swing, she is 0.500 m above the ground. (a) The girl attains the ...
