<h2>Answer:</h2>

<u>The unit represents 100 meters is called </u><u>hectometer</u>

<h2>Explanation:</h2>

The hectometer is not commonly used unit of length in the metric system. This unit is equal to one hundred metres.

The word hectometers comes from a combination of two words "metre" which is unit of length and the SI prefix "hecto-" which means "hundred".

Imagine a 15kg block moving with a speed of 20m/s. Calculate the kinetic energy of this block.

SSSSS [86.1K]

The kinetic energy formula is;

$KE=\frac{m.v^2}{2}$

The variable $m$ represents the mass. Its unit is kilogram. We are informed that the mass of the object is $15kg$ . The variable $v$ represents the linear velocity. Its unit is meter per second. We are informed that the linear velocity of the object is $20m/s$ . Let's find the kinetic energy of the object by substituting these values in the formula.

$KE=\frac{15kg.(20m/s)^2}{2}$
$2.KE=15kg.400m^2/s^2$
$2.KE=(6000)kgm^2/s^2$
$KE=(3000)kgm^2/s^2=3000J$
