Given:
radius of the pendulum = 6 feet
arc length = 14.13 feet
time = 3 seconds
Required:
What is the angular velocity?
Solution:
To compute for the angular velocity, we can use the formula:
w = s/rt
where,
w is the angular velocity
s is the length of the arc
r is the radius of a circle or pendulum
t is the time
substituting the values,
w = 14.13 feet / 6 feet × 3 seconds
w = 0.785 per seconds

Answer:
48
Step-by-step explanation:
48
Let the tens digit be x.
Hence, the units digit will be 2x
Number =10×(x)+(2x)=12x
When 36 is added to the number, the new number formed =12x+36
As the digits are reversed, we can also write the new number as 10×(2x)+x=21x
Hence,
12x+36=10×(2x)+x
⇒12x+36=21x
⇒21x−12x=36
⇒9x=36
⇒x=4
Hence, the original number =12x=12×4=48
