You apply a force of 586 N (215 degree) on an object as it moves over a displacement of 14.8 m (45 degree). What is the work done on the object?

Solution:

In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force.

Work = Force * distance moved in direction of force

$$W = F \cdot \cos \theta \cdot d$$

In our case:

Thus,

$$W = F \cdot \cos \theta \cdot d = 5 8 6 \cdot \cos 1 0 {}^ {\circ} \cdot 1 4. 8 = 8 5 4 1 \mathrm {J}$$

Answer: $W = 8541$ J.
