A block having mass 2.50 kg is pushed 2.80 m all along a frictionless horizontal table by a constant 12.0 N force directed 25.0° beneath the horizontal.
(i) Find out the work done by the exerted force.
(ii) Find out the work done by the normal force applied by the table.
(iii) Find the work done by the force of gravity.
(iv) Find the work done by the total force on the block.
