A force $F = - 5 x$ Newton is acting on a particle and particle goes from $x = 5 m$ to $x = 1 m$ , the work done by this force will be :

Answer:

Solution:

$W = \int_{5}^{1} (- 5 x) d x$

$W = - 5 [\frac{x ^{2}}{2}]_{5}^{1}$

$W = - \frac{5}{2} (1^{2} - 5^{2})$

$W = \frac{5}{2} (25 - 1)$ $= 60 J$
