A block of mass 3.90 kg is pushed 3.80 m along a frictionless horizontal table by a constant 16.0 N force directed 24.0° below the horizontal.
What is th total work done on the block?
16 cos24 N * 3.80 m = 55.5 J
The mass does not matter in the computation of work done, but it does deternmine how fast it accelerates
