Answer:

0.05s

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  = [tex]\frac{time taken}{number of rotation}[/tex]  

    Period = [tex]\frac{2.5}{50}[/tex]    = 0.05s
