Question

The force acting on a particle varies as in the figure below. (The x axis is marked in increments of 1.50 m.)

Find the work done by the force as the particle moves across the following distances.     (a) from x = 0 m to x = 12.0 m
          J
    
    (b) from x = 12.0 m to x = 18.0 m
          J
    
    (c) from x = 0 m to x = 18.0 m

The force acting on a particle varies as in the figure below. (The x axis is marked in increments of 1.50 m.) Find the work done by the force as the particle moves across the following distances. from x = 0 m to x = 12.0 m from x = 12.0 m to x = 18.0 m from x = 0 m to x = 18.0 m

Explanation / Answer

work done = area under graph

A) from 0-12

work done = 1/2 *6*12 =36 J

B) 12-18

work done = 1/2 * 3* 6 =-9J

c) 0-18

work done = 27 J
