Question

A particle moves under the effect of a force F=Kx^2 from x=0 tox=4 the work done by by the force​

Answer 1

Explanation:

We need to integrate F with respect to dx , then Work done by the force =>

$k \frac{ {x}^{3} }{3} \: from \: 0 \: to \: 4 = > k \frac{ {4}^3 }{3} - k(0) = >$

$\frac{64k}{3}$

Hope it helps you.
