A particle moves along the x-axis from $x = 0$ to $x = 5 m$ under the influence of a force given by $F = 7 - 2 x + 3 x^{2}$ . The work done in the process is-

Options:

Answer:

Solution:

$W = \int F . d x = \int_{0}^{5} (7 - 2 x + 3 x^{2}) d x$

$= {[7 x - \frac{2 x^{2}}{2} + \frac{3 x^{3}}{3}]}_{0}^{5}$

$= 35 - 25 + 125 = 135 J$
