Question

A diver completes 212 somersaults during a 2.4 s dive. What was the diver's average angular speed during the dive?

Answer 1

The diver's average angular speed during the dive is 555.01 rads/sec

We are given;

              Time taken; t = 2.4 secs

               Number of somersaults = 212

Now, we know that,

               1 revolution = 2π radians

And number of somersaults is the same thing as number of revolutions

So,

               Total radians = 2π × 212 = 424π

average angular speed = total number of revolutions/time period

                                       = 424π/2.4

                                       = 555.01 rads/sec

Hence the diver's average angular speed during the dive is 555.01 rads/sec.
