Answer:
n = log(
)
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent.

Answer:
and the slope intercept is 
1. The time taken for the water to fall that much is 0.2 s
2. The initial speed of the water is 4 m/s
<h3>1. How to determine the time </h3>
- Height (h) = 20 cm = 20 / 100 = 0.2 m
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) =?
h = ½gt²
0.2 = ½ × 9.8 × t²
0.2 = 4.9 × t²
Divide both side by 4.9
t² = 0.2 / 4.9
Take the square root of both side
t = √(0.2 / 4.9)
t = 0.2 s
<h3>2. How to determine the initial speed</h3>
- Horizontal distance (s) = 80 cm = 80 / 100 = 0.8 m
- Time (t) = 0.2 s
- Initial speed (u) =?
s = ut
Divide both sides by t
u = s / t
u = 0.8 / 0.2
u = 4 m/s
