Answer:
Depth = 7.06 m
Velocity = 11.77 ms-1
Step-by-step explanation:
We use the equation of motion:-
s = ut + 1/2 g where s = distance fallen , t = time , u = initial velocity and g = 9.81 ms^-2 , the acceleration due to gravity.
So s = 0(t) + 1/2 * 9.81 (1.2)^2
= 7.06 m to nearest tenth.
We use another equation of motion to find the final velocity:-
v^2 = u^2 + 2gs where v = final velocity
v^2 = 0 + 2*9.81 * 7.06
= 138.52
v = √138.52 = 11.77 m s-1
Answer:
Therefore,
The greatest number of paper cups that can be completely filled from the water cooler is 446 cups.
Step-by-step explanation:
For Cylinder Cooler
Radius = r₁ = 9 in
Height = h₁ = 22 in
For Cone Cups,
Radius = r₂ = 2 in
Height = h₂ = 3 in
To Find:
Number of Paper Cups = ?
Solution:
For a Cylinder we know that
And For a Cone,
Now number of paper cups that can be completely filled from the water cooler will be given as
Substituting the values we get
Substituting the values we get
Therefore,
The greatest number of paper cups that can be completely filled from the water cooler is 446 cups.
