The angular velocity of a scooter wheel is 20 rad/s. If the diameter of the scooter wheel be 40cm. Calculate the speed of the scooter in m/s?
8m/ s
v = omega * r
so
20 rad/s * 0.2 meter = 4 m/s
8m/s
To calculate the speed of the scooter, we can use the formula:
Speed = Angular velocity × Radius
First, we need to find the radius of the scooter wheel. The diameter is given as 40 cm, so we can find the radius by dividing the diameter by 2:
Radius = Diameter / 2 = 40 cm / 2 = 20 cm = 0.2 m
Next, we can substitute the given angular velocity and radius into the formula to calculate the speed:
Speed = 20 rad/s × 0.2 m = 4 m/s
Therefore, the speed of the scooter is 4 m/s.
