A tension force pulls a block a distance 24 meters along a frictionless, horizontal floor. The block has a mass of 10 kg. If the tension force has a magnitude of 49 Newtons, and is oriented at 20-degrees above the horizontal, what will be the speed of the block after it was pulled this distance? Assume the block started at rest, and report your answer in m/s.

A tension force pulls a block a distance 96 meters along a frictionless, horizontal floor. The block has a mass of 10 kg. If the tension force has a magnitude of 91 Newtons, and is oriented at 20-degrees above the horizontal, what was the work done by the tension force? Give the numerical answer in Joules.

A mass m = 14 kg is pulled along a horizontal floor, with a
coefficient of kinetic friction μk = 0.12, for a
distance d = 5.9 m. Then the mass is continued to be pulled up a
frictionless incline that makes an angle θ = 38° with the
horizontal. The entire time the massless rope used to pull the
block is pulled parallel to the incline at an angle of θ = 38°
(thus on the incline it is...
