Question

A car is rounding a curve that is the arc of a circle with a radius of r . if the car has a constant speed of 10 m/s, and its acceleration is 5 m/s2 , what is the radius of the curve?

Answer 1

The formula to find the radius is R=V^2/A or Radius=Velocity^2/Acceleration so that means
R=V^2/A
10^2/5=R
100/5=R
R=20m
