The force shown in Figure 7-17 moves an object from x = 0 to x = 75 m, where the interval between vertical dashed lines is 25 m.

(a) How much work is done by the force?

(b) How much work is done by the force if the object moves from x = 25 to x = 75 m?

(a) Assuming that the directions of the force and motion are the same, the work is the product of the forse and the distance. You don't say what the force is. We can't read your figure.

If the directions of force and motion are NOT the same, you also have to multiply by the cosine of the angle between them.

(b) This distance moved is 50 m in this case. Use the same prcedure as (a).
