That's the cool thing about free fall. The amount of time it takes to fall remains the same.
In this case, a ball that is simply dropped from rest will fall at the same rate as a ball that had some umph in the horizontal direction.

Answer:
35.7kJ
Explanation:
we can calculate the amount of heat energy required , using this formula
Q = mcθ
where.
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat capacity (units )
θ = change in temperature (Celcius,C or Kelvin K)
Assume Specific heat capacity (c) of water =
mass =0.1 kg
