Work done = Gain in potential energy Area under curve =m g h ⇒ (1/2) × 11 × 100=5 × 10 × h ⇒ h=11 m

Q. A toy car of mass $5 k g$ moves up a ramp under the influence of force $F$ plotted against displacement $x$ . The maximum height attained is given by

$y_{m a x} = 20 m$

$y_{m a x} = 15 m$

$y_{m a x} = 11 m$

$y_{m a x} = 5 m$

Work done = Gain in potential energy
Area under curve $= m g h$
$\Rightarrow \frac{1}{2} \times 11 \times 100 = 5 \times 10 \times h$
$\Rightarrow h = 11 m$
