Answer:
13.10643 ergs
Explanation:
Force F=7 Pounds
Force F is acting in the direction of OB in the triangle OAB
Angle OAB = 30°
Displacement =0A= 8 feet
work done by force acting at angle 30° to the horizontal in moving an object from o to A is W = Fx cosx displacement
= zx los (30°) x 8
16x cos(30°)
= 16x (0.818152) (since cos (30°) = 6.819152)
=13.lo643
