Question

A force Vactor F= (3x square +2x-7) newton acts on a 2 kg body as a result of which the body gets displaced from X equal to zero to x equal to 5 m . the work done by the force will be

Answer 1

Answer:

Explanation: we have known that  W=F*D;

by the above two equations we can write as W=m.a.d;

w=(3x^2+2x-7)*5;

w=15x square +10x-35;
