A stone is dropped freely in a river from a bridge. It taken 5s to touch the water surface in the river. Calculate

- the height of the bridge from the water level
- the distance covered by the stone in 2 s. (Take, g = 9.8 m/s
^{2})

A stone is dropped freely in a river from a bridge. It taken 5s to touch the water surface in the river. Calculate

- the height of the bridge from the water level
- the distance covered by the stone in 2 s. (Take, g = 9.8 m/s
^{2})

Given, u = 0, a = g = 9.8 m/s^{2}, t = 5s

- From equation of motion, h = ut + ⇒
- Distance covered by the stone in t = 2 s ⇒
