The car is moving at a speed of 90 km / h. Find the centripetal acceleration of the point on the wheel farthest from its center. The radius of the wheel is 35 cm.
To find the value of the centripetal acceleration of the indicated points of the wheel, we apply the formula: ac = V ^ 2 / R.
Variables: V – vehicle speed (V = 90 km / h = 25 m / s); R is the radius of the wheel (R = 35 cm = 0.35 m).
Let’s make a calculation: ac = V ^ 2 / R = 25 ^ 2 / 0.35 = 1785.71 m / s2.
Answer: The centripetal acceleration of the indicated points of the wheel is 1785.71 m / s2.
