A 2.98 X 102-kg crate is being pulled across a horizontal surface by a force F which makes an angle of 35.90 above the horizontal. Suppose that the coefficient of kinetic friction is 0.222, what should the magnitude of F be so that the net work done by it and the kinetic frictional force is zero?

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

For which pair of objects would adding the same a

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
