Question

A NASCAR driver weighing 75 kg enters a corner with a radius of 155 meters. If his acceleration is 100 m/s2. What is tangential velocity of the vehicle?

Answer 1

The tangential velocity of the car is 124.5 m/s

Explanation:

The centripetal acceleration of an object in uniform circular motion is given by:

$a=\frac{v^2}{r}$

where

a is the acceleration

v is the tangential velocity

r is the radius of the circle

For the car in this problem, we have:

$a=100 m/s^2$ is the centripetal acceleration

r = 155 m is the radius of the turn

Solving for v, we find the tangential velocity of the car:

$v=\sqrt{ar}=\sqrt{(100)(155)}=124.5 m/s$
