The height of the ceiling in the school gym from the floor is 11.48m.
HOW TO CALCULATE HEIGHT OF A PROJECTILE:
- Using one of the equations of motion as follows:
v² = u² + 2as
Where;
v = final velocity (m/s)
u = initial velocity (m/s)
a = gravitational acceleration (m/s²)
s = distance traveled (m)
According to this question,
- The final velocity (v) of the volleyball is 15m/s
- The initial velocity is 0m/s
- The acceleration due to gravity is 9.8m/s
Using the formula, v² = u² + 2as, the height of the ceiling (s) can be calculated as follows:
15² = 0² + 2 (9.8) (s)
225 = 0 + 19.6s
225 = 19.6s
s = 225/19.6
s = 11.48m
Therefore, the height of the ceiling in the school gym from the floor is 11.48m

Answer:
6.7 to 7.0
Explanation:
In the digestive systems of humans and many other mammals, an alpha-amylase called ptyalin is produced by the salivary glands, whereas pancreatic amylase is secreted by the pancreas into the small intestine. The optimum pH of alpha-amylase is 6.7–7.0.
Answer:
measure average changes in price over time that consumers pay for goods and services.
Cattle depend on microorganisms in their digestive tract to digest the cellulose in their diets. The Cattle and the microorganisms are Symbionts. Since they are not able to digest the cellulose that they eat from plants.
