Just asking help with Part I
A factory worker pushes a 30.0 kg crate a distance of 4.40 m along a level floor by pushing downward at an angle of 28.0° below the horizontal. The coefficient of kinetic friction between the crate and floor is 0.260. The Crate is Pushed with Increasing Speed Now assume that, instead of the previous situation, the worker pushes harder (without changing the direction of his push), so that the crate moves with increasing speed....
