Suppose you start riding your bicycle from rest, and the wheels reach an angular speed of 296 rpm in 4.5 seconds. How many complete revolutions do the wheels make in this time?

To find how many complete revolutions the wheels make in 4.5 seconds, we need to convert the given angular speed from revolutions per minute (rpm) to revolutions per second (rps).

First, let's convert 296 rpm to rps:

1 rpm = 1/60 rps (since there are 60 seconds in a minute)
296 rpm = 296/60 rps ≈ 4.93 rps (rounded to two decimal places)

Now, we can find the number of complete revolutions by multiplying the angular speed (in rps) by the time (in seconds):

Number of complete revolutions = angular speed (rps) × time (seconds)
= 4.93 rps × 4.5 s
≈ 22.19 (rounded to two decimal places)

Therefore, in 4.5 seconds, the wheels make approximately 22.19 complete revolutions.
