Question

Ivy wants to jump unto the merry-go-round at the park. The merry-go-round has a diameter of 4 metres
and makes 14 revolutions every minute. Find the EXACT angular velocity of the merry go round.

Answer 1

Answer:

Angular velocity of the merry go round. = 1.47 radians per second

Step-by-step explanation:

To find the angular velocity, measure their revolutions per minute (n) and radius of (R).

Here R = 2 meters, n = 14

Linear velocity = $\frac{2\pi n }{60}$ R

By substituting the values in the above equatiom, we get

Linear velocity  = 2.93 m/s

Angular velocity = $\frac{2.93}{2}$ = 1.47 radians per second
