Question

Jerry measures the time it took for a ball dropped from a balcony to hit the ground. His stopwatch reads 2.6 s. How high is the balcony?

Answer 1

33.12m

Step-by-step explanation:

Given parameters:

Time of fall = 2.6s

Unknown:

Height of the balcony = ?

Solution:

To solve this problem; use this expression:

H = ut +
`(1)/(2)` gt²

u is the initial velocity

t is the time

g is the acceleration due to gravity = 9.8m/s²

So;

H = (0 x 2.6) + (
`(1)/(2)` x 9.8 x 2.6²) = 33.12m
