Mathematics

The h(t) at a certain period when the penny is dropped in the ground is zero. Substituting the known values in the equation will give us an expression of,
                                   0 = -4.9t² + 0 + 150
v₀ is zero in the assumption that the dropping is free. Solving for t of the equation,
                                          t = 5.53 seconds
