A force F acting on an object varies with distance x as shown here.

The force is in N and x in m. The work done by the force in moving the object from x = 0 to x = 6 m is

A

18.0 J

B

13.5 J

C

4.5 J

D

9.0 J

Text Solution

Verified by Experts

The correct Answer is:
B
`W= int F. dx`= Area under the curve
`=(3xx3) +(1)/(2)xx (3)(3)=13.5 J`
