Question

A particle moves along the x-axis from x=0 tox=5 under the the influence of force given by F=7-2x+ 3x^2. Calculate the work done in doing so

Answer 1

Answer

Step by step explanation:-

Work done= integral F.Displacement

So, after integration u get

7x-x^2+x^3

Now substitute the values of x as5 and 0 respectively and subtract

U get 7*5-25+125-0

Ans= 135J
