kE of particle is initial kE + change in kE Δ kE = work done = area under F-x curve.

Q. The force $F = F \hat{i}$ 0n a particle of mass $2 k g$ , moving along the x-axis is given in the figure as a function of its position $x$ . The particle is moving with a velocity of $5 m / s$ along the x-axis at $x = 0$ . What is the kinetic energy of the particle at $x = 8 m$ ?

34 J

34.5 J

4.5 J

29.4 J

$k E$ of particle is initial $k E +$ change in $k E$
$Δ k E =$ work done $=$ area under $F$ -x curve.
