Answer:
Heating 100 g of water from 10◦C to 50◦C
Explanation:
m₁ ΔT₁ = 2000
m₂ ΔT₂ = 300
m₃ ΔT₃ = 4000
m₄ ΔT₄ = 70
Let us list out what we know from the question.
Initial Velocity
since the piton is 'dropped'.
Vertical Displacement of the piton D = 215 m
Acceleration due to gravity 
Final Velocity 
Using the equation,
and plugging in the known values, we get

Simplifying by taking square-root on both sides gives us 
Thus, the speed of the piton just before striking the ground is 65 m/s.
