A truck is moving on the horizontal road with constant speed $v.$ A ball is thrown from the truck vertical up at speed $u$ $w.r.t.$ truck. What is distance traversed by the truck when ball returns on the truck

A

$\frac {uv}{g}$

B

$\frac {2uv}{g}$

C

$\frac {3uv}{g}$

D

$\frac {uv}{2g}$

Solution

Range $=\frac{2 \mathrm{u}_{\mathrm{y}}}{\mathrm{g}} \times 4 \mathrm{x}$

$\therefore \mathrm{R}=\frac{2 \mathrm{uv}}{\mathrm{g}}$
