if a car travels at 60 kmh and the wheels of the car are a radius of 400 mm, what is the rotational speed of the wheels?Thanks in advance.
By v rω 60 x 1000/3600 400/1000 x ω ω 41.67 rad/sec 2 x π x n 41.67 n 6.63 revolution/sec
The angular speed is related to velocity by v w x r w (or omega) is the angular speed. Firstly, covert the speed of the wheels to m/s (60 000 m / 3600 s) The radius of the wheel is 0.4 m So, the angular speed is v / r in radians per second. I trust you can use a calculator to compute the value. Hope this helps.
