Question

A tire rotates 50 times in 2.5 seconds what is its period?​

Answer 1

0.05s

Step-by-step explanation:

Given parameters:

Number of rotations = 50times

Time taken = 2.5s

Unknown:

Period = ?

Solution:

The period is the time taken for a body to make one complete rotation. It is mathematically expressed as;

Period =
`(time taken)/(number of rotation)`

Period =
`(2.5)/(50)` = 0.05s
