A-Level Physics - Year 1 (AS): A stone is dropped from a bridge 50 m above the water. The initial velocity is zero, and the acceleration is g = 9.81 m/s².
How do you find the time it takes for the stone to fall?

Use the equation s = ut + (1/2)at². For the stone: 50 = 0 + (1/2) * 9.81 * t², t = 3.19 s
