Answer:
Step-by-step explanation:
diameter of the wheel = 14 cm
rotation of the wheel per minute = 3000 times
therefore the distance covered = diameter of the coil x rotation of the coil
by the wheel
= 14 cm x 3000
= 42000 cm = 420 m
we all know ,
speed = distance
time
= 420 m
60 s[1 minute= 60second]
therefore speed = 7 m/s
of wheel
