GREYUIT [131]

Based on scientific data, the stone is accelerated at approximately 10 $m/s^2$ .

<u>Given the following data:</u>

Weight = 5 Newton

Height = 44 meters.

<h3>What is gravity?</h3>

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

<h3>Gravity on planet Earth</h3>

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 $m/s^2$ .

In this scenario, the stone is accelerated at approximately 10 $m/s^2$ .

Answer:

Explanation:

1. $V_{x}$ = $V_{0}$ * cos $\alpha$ ⇒ 16*cos32 ≈ 13.6 m/s (13.56)

2. $V_{y}$ = $V_{0}$ * sin $\alpha$ ⇒ 16* sin32 ≈ 9.4 m/s

3. $y_{max}$ = $\frac{v_{0}^2*sin^2\alpha}{2g}$ = $\frac{16^2*sin^232}{2*9.8}$ (the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
