A block of mass 2.5kg is pushed 2.20m along a frictionless horizontal table by a constant 16.0 N force directed 25.0 degrees below the horizontal. Determine the work done by (a) the applied force, (b) the normal force exerted by the table, (c) the force of gravity and (d) the net force on the block.

(a) W done by the applied force=F.S=FScos(x)
=16*2.2*cos 25
=31.902 J
(b) W done by the Normal force and the (c)force of gravity is= 0 , since it is perpendicular to the dispacement
(d)how to draw the free body diagram?

the galaxies rotate at speeds inconsistent with their obvious mass is for the reason that we do see it all. I am relating to it as being the theoretical Dark Matter. There are very powerful proofs that suggests that darkish subject exist. One the is the inconsistent pace of and obvious mass. darkish subject makes up approximately seventy five% to eighty% of the problem within the Universe...
