A thunderstorm produces wind gusts up to 125.0 km per hour. Assuming that upwards air flows (updrafts) in the thunderstorm have the same speed, what is the largest hail stone you expect to see from this storm? Assume a hail stone is a sphere of ice with density 934 kg m3. The hail stone drops to the ground when vertical updrafts cannot keep it in the air. Until that time it can grow larger as water freezes on its surface. Enter the diameter of the largest possible hail stone, in m, in TopHat, not including the units. g = 9.81 m s2 You need to collect some additional information from the textbook or notes. For example, the problem does not tell you which formula for air drag to use. You need to find this out yourself
