Answer:
4.45 m/s
Step-by-step explanation:
Vertical distance, Sy = 5m
The speed of pebble when they hit her window :
Vx = Sx / t
We can obtain t using the relation :
Sy = 1/2 * at²
Where, a = acceleration due to gravity = 9.8m/s²
We can obtain t
5 = 1/2 * 9.8 * t²
5 = 4.9t²
t = √5/4.9
t = 1.01 seconds
Hence,
Speed, Vx = Sx / t
Vx = 4.5 / 1.01
Vx = 4.45 m/s
Answer: $88.90
Step-by-step explanation:
Let her initial deposit be represented by x.
Based on the information given, in the question, an equation can be formed as:
x + $25.50 + $45.25 - $15.15 - $28.65 = $115.85
x + $70.75 - $43.80 = $115.85
x = $115.85 + $43.80 - $70.75
x = $88.90
The initial deposit is $88.90
24, 31, 38, 45, 52, 59, 66, 73, 80
Square root of eight (2.83), pi (3.14), 4
