The discussion revolves around the conditions under which hailstones may melt upon impact with the Earth's surface, particularly focusing on the implications of high velocities, such as 824 m/s, and the transformation of kinetic energy during the impact.
The discussion is ongoing, with participants questioning the assumptions about the impact speed and energy distribution. Some suggest that the high velocity required for melting may not be typical for hailstones, while others are seeking clarification on the mechanics involved.
There is a noted lack of specific data regarding the impact speed of hailstones and the conditions under which they strike the ground, which may influence the discussion.
Do you mean to say the hailstones would melt? Or wouldn't melt?dobbygenius said:
yes, the hailstones would melt...but I don't know how to elaborate on thatPeroK said:
You're right I just followed what the question saidPeroK said:
With what speed do hailstones hit the Earth?dobbygenius said:
the first question asked to find the minimum speed for it to melt when it hits the surface and I found it to be 824 m/s but other than that both the first and second question didn't give any more dataPeroK said:
Do you think hailstones hit the ground at ##824 \ m/s## or more? Have you ever seen hailstones?dobbygenius said:
Your reasoning is backwards. If it requires a very high velocity to melt the hailstones then that makes it relatively unlikely that hailstones would melt in practice.dobbygenius said:
Because most of the inelastic deformation would be in the ice.PeroK said:
That's a subtle assumption. It depends what the hailstones hit. Large hailstones may damage a car roof, for example, causing inelastic deformation of the metal.haruspex said:
No, I just looked it up, should've done it earlierPeroK said:
Right...thankyou!haruspex said:
