Question

A stone drops from the edge of a roof. it passes a window 2 m high in 0.1 second . How far is the roof above the top of the window ?

Answer 1

AS WE KNOW THAT
H = - 1/2 GT^2 WHILE FALLING
THEN LET THE DISTANCE BETWEEN WINDOW AND ROOF BE X
THEN
-H = - 1/2× 10× 0.1 ×0.1
H = 5 × 0.01
H = 0.05 M
THEREFORE
ROOF IS 0.05 M ABOVE THE WINDOW
