Mechanical energy is a form of energy, it represents the energy that is possessed by a mechanical system of device due to its motion or position. Stated differently, mechanical energy is the ability of an object to do work. Mechanical energy can be either kinetic (energy in motion) or potential (energy that is stored)

If a student flicks a stationary 0.1 kg ball with 5N of force for 0.1 seconds. What is its final

Alisiya [41]

5m/s

Explanation:

Given parameters:

Mass of ball = 0.1kg

Force on the ball = 5N

time taken = 0.1s

Unknown:

final speed of the ball = ?

Solution:

According to newton's second law "the net force on a body is the product of its mass and acceleration".

Force = mass x acceleration equation 1

Acceleration =

V is the final velocity

U is the initial velocity

T is the time taken

U = O since it is a stationary body;

a = $\frac{V}{T}$

Input "a" into equation 1

F = m x $\frac{V}{T}$

5 = 0.1 x $\frac{V}{0.1}$

V = 5m/s

The standard metric unit of density for a solid is

prisoha [69]

There is no SI "base unit" of density.
(Any unit of mass) divided by (any unit of volume) is
a valid unit of density.

The units of density that are seen most often are

(gram per cm³) and (kgm per meter³) .

Which of the following would likely be the best reflector of heat energy

mr Goodwill [35]

Ok so B would be the best surface to reflect heat energy as it's polished and does not disturb the wave of energy like the others would. Also in therms of colour it's better because it's a lighter colour than navy ( the darker colour of the spectrum ). This matters as darker colours absorb light where light colour reflect it.
Hope this helps :).
