The average speed of the yo-yo is π m/s.
What is average speed?
Average speed is a measure of the rate of change in the position of an object over a period of time. It is typically expressed in units of distance per unit of time, such as kilometres per hour (kph) or metres per second (m/s). Average speed is calculated by dividing the total distance travelled by the total time taken. It is important to note that average speed is not the same as instantaneous speed, which is the current speed of an object at a given moment in time.
The average speed of the yo-yo can be calculated by dividing the circumference of the circle (2πr) by the time it takes to complete one rotation (0.50 s).
2πr/0.50 s = 2π(0.25 m)/0.50 s
= 2π(0.25 m)/0.50 s
= π m/s
Therefore, the average speed of the yo-yo is π m/s.
