Question

A ball is dropped from a bridge 125m above a river. 2sec later a second ball is thrown

straight down. The initial velocity of second ball so that both hit the water surface

simultaneously; is (10n/3)m/s then n is​

Answer 1

Answer:

n will be equal to 8.

Explanation:

using the equation of motion for both the particles and assuming

$t2 = 2 + t1$

Where t2 is time taken by 2nd ball and t1 is time taken by first ball to reach the water surface.
