The acceleration due to gravity on the planet $\mathrm{A}$ is 9 times the acceleration due to gravity on planet B. A man jumps to a height of $2 \mathrm{~m}$ on the surface of A. What is the height of jump by the same person on the plane $\mathrm{B}$ ?
$2 / 9 \mathrm{~m}$
$18 \mathrm{~m}$
$6 \mathrm{~m}$
$2 / 3 \mathrm{~m}$
Solution
Height of jump on the planet B $=\frac{g_{\mathrm{A}}}{g_{\mathrm{B}}} \times$ height of jump on the planet A
$=2 \times 9=18 \mathrm{~m}$
