Another Explanation (5):
Let's calculate the radius of the circular path. 🚗💨
Given:
* Speed, \(v = 72\) km/h \( = 72 \times \frac{1000}{3600}\) m/s \( = 20\) m/s
* Centripetal acceleration, \(a_c = 1\) m/s\(^2\)
We know the formula for centripetal acceleration is:
\[a_c = \frac{v^2}{r}\]
Where:
* \(a_c\) is the centripetal acceleration
* \(v\) is the speed
* \(r\) is the radius of the circular path
We need to find \(r\), so we rearrange the formula:
\[r = \frac{v^2}{a_c}\]
Now, plug in the given values:
\[r = \frac{(20 \text{ m/s})^2}{1 \text{ m/s}^2} = \frac{400 \text{ m}^2/\text{s}^2}{1 \text{ m/s}^2} = 400 \text{ m}\]
Therefore, the radius of the circular path is 400 meters. ✅
