Question

The only force acting on a 2.0 kg body as it moves along a positive x-axis has an x-component fx= -6x with x in metres. The velocity at x=3.0m is 8.0m/s. What is the velocity of the body at x=4.0m?

Please show the working too if possible.

Answer 1

Explanation:

hope it helps handwriting is lil fizzy

Answer 2

Explanation:

v=root 95

see first of all you must know that this force is a variable force.

So work done by a variable force is:w=integration of f(x)dx

And we also know work done by net force is change in kinetic energy.
