Answer:
<h2>1.84feet</h2>Step-by-step explanation:
Using the formula for finding range in projectile, Since range is the distance covered in the horizontal direction;
Range
U is the velocity of the arrow
H is the maximum height reached = distance below the bullseye reached by the arrow.
R is the horizontal distance covered i.e the distance of the target from the archer.
g is the acceleration due to gravity.
Given R = 60ft, U = 250ft/s, g = 32ft/s H = ?
On substitution,
Squaring both sides we have;
The arrow will hit the target 1.84feet below the bullseye.
Answer:
feet per second is the differential equation
Step-by-step explanation:
Given:
The radius of the cylindrical tank= 2 feet
The height of the cylindrical tank = 10 feet
The radius of the circular hole = 3/4 inches
To Find:
The differential equation for the height h of the water at time t.
Solution:
<u>Finding the surface area(A) of the tank</u>
Surface area =
On substituting the values
Surface area =
= square feet
<u>Finding the surface area(a) of the hole</u>
The radius is given in inches, so converting into feet we have
1 inch = 0.083 foot
similarly
= 0.0625 feet.
Now the surface area,
=
= square feet
Now let the velocity of water through the hole is v
According law of conservation of energy, the penitential energy due to the height h of the water gets converted into kinetic energy.
The rate of water flowing through the hole is =
= >
At any time t
On substituting the values, we get
feet per second
