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:
Kinetic energy is the energy an object possesses due to its motion. It is calculated by multiplying the mass of the object by the square of its velocity, and is measured in joules (J).
Hail stones have kinetic energy because they are in motion as they fall from the sky. The larger and heavier the hail stone, the more kinetic energy it will have.
The kinetic energy of a hail stone can be calculated using the equation KE = 1/2 * m * v^2, where m is the mass of the hail stone and v is its velocity.
Yes, the kinetic energy of hail stones can cause damage when they collide with objects on the ground, such as buildings, cars, and crops. The amount of damage depends on the size and velocity of the hail stones.
The kinetic energy of hail stones affects their trajectory by determining how far they can travel and how fast they can fall. Hail stones with higher kinetic energy will typically have a more vertical trajectory and fall faster than those with lower kinetic energy.
