A 2-kg object is dropped from a height of 10 meters. Using the formula (use g=10m/s2), the potential energy is calculated as . If the object strikes the ground with a speed of 5 m/s, then using the formula , the kinetic energy is 100 joules. This requires that of energy is turned into and eventually released to its surroundings.

Total of 175 J of energy is turned into and eventually released to the surroundings

Explanation:

The potential energy is mgh = 2 * 10* 10 = 200

Kinetic energy = 1/2 mv^2 = 0.5 *2 * 5 *5 = 25

Loss in energy = 200 -25 = 175

Total of 175 J of energy is turned into and eventually released to the surroundings
