Question

A ball is dropped from a height h above ground. Neglect the air resistance, its velocity (v) varies with its height above the ground as (A) √2 g(h-y) (B) √2 g h (C) √2 g y (D) √2 g(h+y)

Tardigrade Admin · Accepted Answer

Correct answer is (a) √2 g(h-y)

Q. A ball is dropped from a height $h$ above ground. Neglect the air resistance, its velocity $(v)$ varies with its height above the ground as

$2 g (h - y)$

$2 g h$

$2 g y$

$2 g (h + y)$

Correct answer is (a) $2 g (h - y)$

Q. A ball is dropped from a height h above ground. Neglect the air resistance, its velocity (v) varies with its height above the ground as

2g(h−y)​
