Jasmine is riding on a carousal. She is sitting 9.5 feet from the center and it takes 20 seconds to complete a rotation. What is Jasmine's linear speed (rounded to the nearest tenth)?

2.983 ft/sec

Step-by-step explanation:

Given that

Distance between center and Jasmine riding on a carousal = 9.5 feet

Time taken to complete one rotation = 20 seconds

To find:

Jasmine's linear speed = ?

Solution:

Number of revolutions per minute =

Formula for linear speed is given as:

Where is the radius of circular path and

is the number of revolutions per minute.

Therefore, the linear speed is 2.983 ft/sec.

the correct answer is 1: 2
