A4.00 kg stone is dropped from a height of 145 m. what is the stone's potential and kinetic energy respectively when it is 50.0 m from the ground?

D - 1,960 J, 3,720 J

At a height of 50 m from the ground, the potential energy will be;

= 4 × 9.8 × 50

= 1960 Joules

This means that some of the energy possessed by the stone at a height of 145 m was converted to kinetic energy.

Therefore; the energy that was converted to kinetic energy will be;

= 5,680 J - 1960 J

= 3,724 Joules

Approximately kinetic energy is 3,720 Joules

Therefore;

The Potential energy is 1960 Joules and Kinetic energy is 3,720 Joules

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

answer; the correct answer is technician a; ///100%good luck
