What is the radius of a car wheel if, when driving at a speed of 36 km / h, a centripetal acceleration of 250 m / s acts on the extreme points of the wheel.
To find the value of the wheel radius of the specified car, we will use the formula: ac = V ^ 2 / R and R = V ^ 2 / ac.
Values of variables: V – speed of the specified vehicle (V = 36 km / h = 10 m / s); ac – centripetal acceleration acting on the extreme points of the wheel (ac = 250 m / s2).
Calculation: R = V ^ 2 / ac = 10 ^ 2/250 = 0.4 m.
Answer: The wheel radius of the specified vehicle is 0.4 m.
