<h2>Answer: False</h2>

Explanation:

This sentence is the description of the mechanical energy.

In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.

That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).

In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>

Therefore:

<h2>The sum of potential and kinetic energies in the particles of a substance is called  <u>Mechanical Energy</u></h2>

nordsb [41]

Answer:

W=3456 N

Explanation:

Force 1 F_1=3456

Force 2 F_2=2333N

Acceleration at stage 2 a_2=0.39

Generally the weight of the Craft W is given as

W= upward force(thrust)

Therefore

W=3456 N

Georgie was pulling her brother (of mass 16 kg) in a 9.4 kg sled with a constant force of 39 N for one block (128 m). How much w
Genrish500 [490]

Answer:

4992 J

Explanation:

Force, F = 39 N

Distance, s = 128 m

Work done = force x distance

W = 39 x 128

W = 4992 J

Thus, the work done is 4992 J.
