The body freely falls from a height of 10 m what is the kinetic energy at a height of 6 m.

h initial = 10 m;
h = 6 m;
m = 0.1 kg.
Find: K
We use the formula mghinit = K +. mgh.
Let us express K.
K = mg (h start – h).
Substitute all known values (considering that g = 10 m / s ^ 2).
K = 0.1 * 10 * (10-6) = 4 J.
