m= 5kg
When it is halfway down,
h= 10/2=5m
Loss in PE=Gain in KE
mgh= KE
5×10×5= KE
KE=250J

Answer:
The kinetic energy will be 490 J.
Explanation:
Given that,
Mass of the object m = 5 kg
Height h = 10 m
We know that,
Loss in potential energy = gain in kinetic energy
Here, m = mass
h = height
Hence, The kinetic energy will be 490 J.
