in (8a) A block of mass 2.50 kg is pushed 2.09 m along a frictionless horizontal table by a constant 18.8N force directed 27.8 below the horizontal. Determine the work done by the applied force (in Joules). Tries 0/10 (8b) Determine the magnitude of the normal force exerted by the table. 1:] Tries 0/10 (8c) Determine the magnitude of the force of gravity. [: Tries 0/10 (8d) Determine the magnitude of the net force on the block. [: Tries 0/10
