Question

Help me please

A block of mass m = 3.10 kg is pushed a distance d = 6.60 m along a frictionless, horizontal table by a constant applied force of magnitude F= 16.0 N directed at an angle theta = 28.0 degree below the horizontal as shown in the figure below. (a) Determine the work done on the block by the applied force. (b) Determine the work done on the block by the normal force exerted by the table. (c) Determine the work done on the block by the gravitational force. What is the angle between the force of gravity and the displacement? (d) Determine the work done by the net force on the block.

Explanation / Answer

W_applied force= F*cos(theta)*d = 93.23J

W_normal force = 0 (displacement along y axis = zero)

W_gravitational force = 0 (displacement along y axis= zero)

Angle = 90degree(between force of gravity and displacement)

W_net force = W_F cos(theta)+ W_F sin(theta) = 93.23 + 0 =93.23 J
