Question

an object r the ground from a height of 5m on a planet ,what is the value of g on the planet​

Answer 1

◆◆ANSWER◆◆

■ GIVEN THAT:-

▪︎Time(t)=5 seconds and height(h)=5m

■ TO FIND:-

▪︎gravitational acceleration of the planet .

We know that,

$s = ut + \frac{1}{2} g {t}^{2}$

▪︎So,now putting the value of time and height.

$5 = 0 \times 5 + \frac{1}{2} g(5)^{2}$

$5 = \frac{1}{2} g \times 25$

$g = \frac{2}{5}$

$g = 0.4 \: square \: metre$

▪︎The gravitational acceleration of the planet is 0.4 m/s^2
