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 final velocity of the stone?

Question

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 final velocity of the stone?

daavide · Accepted Answer

Use the equation v² = u² + 2as. For the stone: v² = 0² + 2 * 9.81 * 50, v = 31.3 m/s
