A stone is droppe

Answer :

Horizontal velocity = = 60 kmhr–1

Height of the window = H = 1.96 m

Horizontal range = ?

Now, we know that:

R = Horizontal Range = Distance along the track stone

makes before striking ground

So, where T = time of flight

Using equations of motion:

Now, for t = T

= g

= H (Vertical Distance)

= 0 (Initial vertical Speed)


Now, = 60 kmhr–1 =
