A man on a high cliff He threw the stone down at a speed of 10m/s The stone takes 5s, so it falls to the ground. find the height of cliff.

175 m

Explanation:

Taking down to be positive, given:

v₀ = 10 m/s

a = 10 m/s²

t = 5 s

Find: Δy

Δy = v₀ t + ½ at²

Δy = (10 m/s) (5 s) + ½ (10 m/s²) (5 s)²

Δy = 175 m
