Easy Depth Density Question Will Pick Best Answer?

Question

A small ball 0.51 times as dense as water is dropped from a height of 14m above the surface of a smooth lake. Determine the maximum depth to which the ball sinks. Disregard any energy transferred during impact and sinking. Answer in meters.

Answer 1

0.51*14m = 0.49*h, hence h = 15m (two significant figures!)
