Question

The wheel of a car has a radius of 0.413 m. If the wheel rotates at 456 revolutions per minute, what is the speed (in m/s) at which the outer edge of the wheel is moving

Answer 1

Answer: The speed of the edge of the wheel = 19.72m/s

Explanation:

The liner speed of the edge of the wheel is given as;

V=wr

V= linear speed =?

w= angular velocity =456rpm

Converting rpm to rad/s

1rpm = π/30 rad/s

456rpm = 47.75 rad/s

r=0.413m

V=47.75 × 0.413

V= 19.72m/s

Therefore speed of the edge of the wheel = 19.72m/s

Answer 2

Answer:

The speed (in m/s) at which the outer edge of the wheel is moving is 19.722 m/s
