Question

a body of Mass 8kg is moving with a velocity of 5m/s at a height of 10m. calculate the total energy possessed by the body ...formula and explanations please ​

Answer 1

Explanation:

total energy = KE + PE

= PE ( potential energy ) = mgh

= 784 J

KE ( kinetic energy ) = 1/2 mv²

= 1/2 × 8 × 5²

= 4×25

= 100 J

therefore, total energy = 784+100 J

= 884 J

potential energy is the energy possesed by an object when it is at a certain height

kinetic energy is the energy possesed by an object when it is moving with some velocity.

SI unit of energy = J ( joules )

hope it helped :)

Answer 2

Answer:

The answer is 884 J

Explanation:

Total Energy is the sum of all final energy used at a certain branch or variable. Because energy data is recorded directly rather than as the result of an activity level and an energy performance, total energy can be distinguished from final energy intensity. You may calculate joules by dividing the quantity of watts by the number of seconds. The total of kinetic and gravitation potential energy makes up a system's total energy, which is conserved during orbital motion. To leave a planet and not come back, an object must have a minimal velocity known as the escape velocity.

total energy $= KE + PE$

                    $= PE = mgh$

                    $= 784 J$

$KE = 1/2 mv^{2}$

      $= 1/2 * 8 * 5^{2}$

      $= 4*25$

      $100J$

therefore, total energy $= 784+100 J$

                                      $= 884 J$
