Step-by-step explanation:
We are given that a variable force of magnitude F(x) moves a body along the x- axis from
to
.
The net work done by the force in moving the body from
to
.
=Velocity of the body at 
Velocity of the body at 
We know that
Work done=Final kinetic energy-Initial kinetic energy

K.E=

Hence, the net work done by the force is given by

Answer:

Step-by-step explanation:

2(x+5)=2x+10
(2x+10)(3x-2)=
2x(3x)+10(3x)+2x(-2)+10(-2)
=
=
