Answer 1

$\huge \sf \fbox \green{answer}$

20 to 130 km/h

Step 1: Compute derivative. The first step to finding curvature is to take the derivative of our function, ...

Step 2: Normalize the derivative. ...

Step 3: Take the derivative of the unit tangent. ...

Step 4: Find the magnitude of this value. ...

Step 5

$Divide \: this \: value \: by ∣ ∣ v ⃗ ′ ( t ) ∣ ∣ ||\vec{\textbf{v}}'(t)|| ∣∣v ′(t)∣∣$
