Ben has just bought a new bike with 23 inch wheels but without mudguards and he decided to test it despite the fact it was raining. Find the maximum height of the raindrops which were being flicked up from the back wheel if his speed was 18 km/h. Where were the drops when they reached the highest point relative to the bike?
