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
If the theatre sold 225 seats out of 250, that is the 225/250. To find the percent of the fraction, you have to divide the numerator by the denominator. You get 0.9. This is a decimal. Multiply the decimal by 100 to get a percent. If you multiply 0.9 by 100, you get 90. So, if the stage is 90% full, it is 10% empty.
The answer is that the stage is 10% empty.
