2. An object is moving in the positive x-direction while a net force directed along the x-axis is exerted on the object. The figure shows the force as a function of position. What is the net work done on the object
over the distance shown?
F
FO
o
2d
3d
-Fof
A) Fid
B) Ford
C) 2Fd
D) 4F,

A. F₀d

Explanation:

The formula for work done on an object is given by:

w= f*d

Work done towards the positive direction is given by ;

Work done under the trapezoid shaped area:

1/2 {a+b} h = 1/2 { 2d + d } F₀

W=3/2dF₀

Work done on the triangle shaped part

W= 1/2 * b * h

W= 1/2 * d * -F₀ =  -1/2dF₀

The net work done :

3/2dF₀ -1/2dF₀ = 1dF₀

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
