Question

A coin is dropped from a balcony 52.8m / h * i * g * h . How long does it take the coin to land in the fountain below ?

Answer 1

Given data:

* The height of the balcony is 52.8 m.

* The initial velocity of the coin is zero.

Solution:

By the kinematics equation, the time taken by the coin to land on the fountain is,

$H=ut+\frac{1}{2}gt^2$

where H is the height, g is the acceleration due to gravity, u is the initial velocity, and t is the time taken,

Substituting the known values,

$undefined$
