Question

A stone dropped from the top of a tower of height h after 1 second another stone is dropped from the balcony 20 below the top both reach the bottom simultaneously what is the value of h take g is equal to 10 metre per second square

Answer 1

Step-by-step explanation:

let the height be hm

time taken be ts

for 1st stone:

h=1/2gt**2••••••1 equation

for 2nd stone:

h-20=1/2g(t-1)**2••••••2 equation

from equation 1 and 2

t=2.5s

putting the value of t in equation 1

h=-31.25m
