A10.0kg crate is pulled up a rough incline with an initial speed of 1.5 m/s. the pulling force is 100.0n parallel to the incline, which makes angle of 15.0° with the horizontal. assuming the coefficient of kinetic friction is 0.49 and the crate is pulled a distance of 7.5m, find the following:

b.) the work done by the force of friction on the crate

c.) the work done by the puller on the crate

Employer informs its employees that it will hold a substantial cash prize drawing for each work group at the end of each month in which no employee in the work group sustains a lost-time injury. tyra reports an injury that she sustained while operating a mechanical power press. tyra did not violate any employer safety rules when she sustained her injury. tyra’s injury requires her to miss work for two days. her employer cancels the cash prize drawing for that month for tyra’s work group because of tyra’s lost-time injury. did the employer misuse an incentive program to retaliate against tyra?
