A student on an amusement park ride moves in a circular path with a radius of 3.5 meters once every 8.9 seconds. What is the average speed of the student

Respuesta :

Distance traveled by him = circumference of that circular path = 2πr = 2π(3.5)
= 7π = 7×3.14 = 21.98 m
time = 8.9 s  [ Given ]

Now, Average speed = distance / time
s = 21.98 / 8.9
s = 2.46 m/s

Hope this helps!
