Answer : The volume of water in the pool is, 2473 ft³
Explanation :
First we have to calculate the average depth.
Given:
Diameter = 30 ft
Depth range : 1 to 6 ft linearly
average depth =
Now we have to calculate the volume of water in the pool.
Volume = area × average depth
V = π × (radius)² × 3.5
V = π × (30/2)² × 3.5
V = π × (15)² × 3.5
V = π × 225 × 3.5
V = 3.14 × 225 × 3.5
V = 2472.75 ft³ ≈ 2473 ft³
Therefore, the volume of water in the pool is, 2473 ft³
Answer:
Mass of second object will be 15 kg
Explanation:
We have given mass of first object = 12 kg
Acceleration 
According to second law of motion we know that force F = MA
So force 
As the same force is applied to the second object of acceleration 
So force = ma
m = 15 kg
So mass of second object will be 15 kg
Explanation:
by the formula, v²-u²=2aS
S=12m, a=2m/s², v=25m/s, u=?
v²-u²=2aS
25²-u²=2×2×12
-u²=48-625
-u²=-577
u²=577
u=√577
u = 24.02m/s
