Problem

A 0.80-kg puck moves on a frictionless horizontal surface while a horizontal force given by

F(x)=4x+2

(in newtons, with

x

in meters) acts on it from

x=0

x=3\,\text{m}

. What is the work done by the force over this interval? (a)

36\,\text{J}

(b)

18\,\text{J}

(c)

24\,\text{J}

(d)

20\,\text{J}
