Answer :
Answer:
Jack's linear speed is 126ft/min
Bob's linear speed is 176ft/min
Step-by-step explanation:
First of all, find the circumference of both circles given the radius; Jack, 2pir (10)=63ft. Bob 2pir(14)=88ft. Now, realize that the merry go round revolves 2 times per min; 2rpm, so multiply each result by 2 and there you go.
A merry go round revolves 2 times per minute, jack is 10 feet from the center while bob is 14 feet from the center
Given
Jack's linear speed is 126ft/min
Bob's linear speed is 176ft/min
What is Circumference of Circle?
The circumference of a circle is the inshort perimeter of that given circle. i.e. the total length of the boundary of the circle. The circumference of any circle is the product of constant π & the diameter of that given circle.
Circumference of Circle= [tex]2 \rm \pi r[/tex]
First of all, we have to find the circumference of both the given circles where radius
Jack 2times per min (10)=63ft.
Bob 2 times per min(14)=88ft.
Now, we can understand that the merry go round revolves 2 times per min; 2 rpm, so multiply each result by 2 and there you go.
