The force on a particle as the function ...

The force on a particle as the function of displacement x is given by `F = 9 + 0. 3x`. The work done corresponding to displacement of particle from x = 0 to x = 2 unit is

A

18.6 J

B

21 J

C

25 J

D

9.6 J

Text Solution

Verified by Experts

The correct Answer is:
A
`W= sum dW = int_(0)^(2)f dx = int_(0)^(2)(9+0.3x)dx=9+(0.3x^(2))/(2)int_(0)^(2)`
= 18.6 J.
