It takes a student t = 7.6 s to push a block m = 11 kg at a constant velocity over a distance of d = 8.2 m. The coefficient of friction between the block and the ground is ? = 0.38.
a) Write an expression using the variables provided for the force applied by the student Fs.
b) Write an expression for the energy required to move the block along this path in terms of the variables provided.
c) How much power was applied to the block in Watts?
