Step-by-step explanation:
<h2>1. kinetic energy = 1/2 mass× velocity²</h2>
mass= 5.2. velocity =2.4
thus, 1/2 × 5.2×2.4×2.4
<h3>= 14.97joule</h3>
<h2>2. potential energy = mass× acceleration × height </h2>
mass=5.2. height=5.8 g=9.8
=5.2×5.8×9.8
<h3>= 295.5 joule</h3>
<h2>3. mechanical energy = potential energy + kinetic energy </h2>
= 295.5+14.97
<h3>=310.47 joule</h3>
hope it helps :)
These are the steps and the answer
An equilateral polygon has congruent sides, like a rhombus.
An equiangular polygon has congruent interior angles, like a rectangle.
In other words: Equilateral doesn't necessarily have congruent INTERIOR angles while equiangular does have/need congruent interior angles.
