What is the kinetic energy of a 3 kg stone if it was thrown at a speed of 10 ms?

m = 3 kg;

v = 10 m / s;

Ek -?

Let’s find the kinetic energy of the stone using the formula:

Ek = (mv ^ 2) / 2, where m is the mass of the stone, v is the velocity of the stone squared.

Then, Ek = (3 kg * (10 m / s) ^ 2) / 2 = 150 J (kinetic energy is measured in joules).

Answer: the kinetic energy of the stone is 150 J.
