A25 newton force applied on an object moves it 50 meters. the angle between the force and displacement is 40.0 degrees. what is the value of work being done to the object? a) 0 joules b) 9.6 x10^2 joules c) 1.2 x10^3 joules d) -9.6 x10^2 joules e) 1.2 x10^3 joules

Work done is when a force is exerted to cause a displacement in a certain object. 
the equation for work done ;
work done = force applied * displacement of the object 
when the force applied is not in the same direction as that of the displacement of the object then the effect of the force is not its whole value. The force is then applied at an angle to that of the displacement of the object, then the resultant force is the force exerted* cos of the angle between force and displacement, in this instance the angle is 40 °.
the new equation is then;
work done = force cos 40° * displacement
after substitution,
work = 25 N * 0.76 * 50 m
         = 957.55 J
round it off
         = 9.6 *10² J
the correct answer is B
