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

Free Chegg Answer 1

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

Free Chegg Answer 2

• a) Work done = area under the curve = 12*6/2 = 36 joule

  b) 6*(-4) /2 = -12 joule

  c) Total work 36-12 = 24 joule

•  
   

  a) taking x=12 m at C

  work done is area under area so work

  =6*12/2= 36 N

  b) from x = 12.0 m to x = 18.0 m

  = -2*(18-12)/2= -6 N

  (c) from x = 0 m to x = 18.0 m

    =6*12/2-2*(18-12)/2

  = 36 N-6 N =30N
