A ball weighing 100 g falls vertically down from a height of 6 m.If we neglect the air resistance

A ball weighing 100 g falls vertically down from a height of 6 m.If we neglect the air resistance, then the kinetic energy of the ball before hitting the ground is …

First, let’s calculate what value the potential energy of this ball will equal when it was at a height of 6 meters, if from the condition of our problem we know for sure that its mass is 100 grams:

100 grams – this will be equal to 0.1 kilogram;

Ep = m * g * h;

0.1 * 10 * 6 = 6.

As we know from the school physics course, in our case, before the ball hits the ground, all its potential energy will make a transition to kinetic energy, that is:

Ep = Eк.

Answer: It will be equal to 6 J.
