1. A carnival ride has a radius of 10.00 m and rotates at a speed of 3.00 m/s. Find the period of one complete revolution.
Given:
r=
v=
Unknown:
T=?
Equation:
v=2*pi*r/T

Answer 1

21s

Step-by-step explanation:

Given parameters;

Radius = 10m

Speed or velocity = 3m/s

Unknown:

Period = ?

Solution:

To solve this problem, use the expression:

v =
`(2\pi r)/(T)`

r is the radius

T is the unknown

Input the parameters and solve for T;

3 =
`(2 x \pi x 10)/(T)`

62.84 = 3T

T = 21s
