You need to find the acceleration . a=v-vo/t
a=6-10/4
a=-4/4
a=-1m/s/s or -1m/s^2
You’re welcome :)
The horizontal distance that the cannonball will travel is 383.33m
In order to find the horizontal distance, we will use the formula for calculating the range expressed as:
where:
u is the velocity
H is the height
g is the acceleration due to gravity

Hence the horizontal distance that the cannonball will travel is 383.33m

Circumference of a circle can be calculated if the radius or the diameter is given.
<u>Explanation</u>:
- Circumference or the perimeter of a circle can be calculated if the radius or the diameter of the circle is given.
- This is calculated by the formula - 2 * pi * r (if radius is given) and pi * d (if diameter is given) where pi = 3.14, r = radius and d = diameter
- This calculation is based on the fact that the circumference is three and a little more times that of the radius. Since the diameter is double that of the radius, when the diameter is given formula becomes pi*d.
Use v = u + at
