Length of hole (s) = 362.77 m (Approx)

Explanation:

Given:

Time taken to hit the bottom (t) = 8.6 s

Acceleration due to gravity (g) = 9.81 m/s²

Find:

Length of hole (s) = ?

Computation:

Initial velocity (u) = 0 m/s

S = ut + 1/2 (gt²)

S = (0) (8.6) + 1/2 (9.81) (8.6) (8.6)

S = 1/2 (9.81) (8.6) (8.6)

S = 1/2 (9.81) (8.6) (8.6)

S = 362.7738

Length of hole (s) = 362.77 m (Approx)
