A miner of mass 90 kg travels down the slide.
Vertical drop = 15m
a) Calculate the maximum possible speed that the miner could reach at the bottom of the slide.
b) The speed of the miner at the bottom of the slide is much less than the calculated maximum possible speed. Explain why.

The easy way is to consider the conversion of gravitational potential energy (mgh) to kinetic energy 1/2 mv^2

that gives you a maximum limit to the final speed... Realistically there will be losses to friction etc.
