Question

A watermelon dropped from a height of 100 feet above wil be at a height of s feet after falling for t seconds, according to this formula:______.
s(t)_____________.

Answer 1

Explanation:

velocity of a freely falling body is given as

$v= \sqrt{2gh}$

h= height and g= acc. due to gravity = 32ft/sec^2.

now, t secs the object at height of s feet its velocity

$s=ut +gt^2$

here u= initial velocity =0,

therefore,

$s=gt^2$
