Question

At some planet 'g' is 1.96 m/s?. If it is safe to jump from a height of 2
m on earth, then what should be corresponding safe height for
jumping on that planet? (Take 'g' for earth is 9.8 m/s)​

Answer 1

Answer:

Safe Height = 10m

Explanation:

Here we will use, m1g1h1 = m2g2h2

Mass is constant on both planets = m1 = m2

g1 = 1.96m/$s^{2}$

g2 = 9.8m/$s^{2}$

h1 = ?

h2 = 2m

g1h1 = g2h2

H1 x 1.96 = 9.8 x 2

H1 = $\frac{9.8 x 2}{1.96}$ = 10m
