Question

A race car goes around a level, circular track with a diameter of 1.00 km at a constant speed of 101 km/h. What is the car's centripetal acceleration in m/s2? answer in:___m/s2

Answer 1

We can find the centripetal acceleration as follows:

`\begin{gathered} a_c=(v^2)/(r) \\ where: \\ v=101km/h=28.0556m/s \\ r=(diameter)/(2)=(1000m)/(2)=500m \\ so: \\ a_c=((28.0556^2))/(500)=1.5742m/s^2 \end{gathered}`

Answer:

1.5742 m/s²
