Question

A race car goes around a 200 m Radius curve at a constant speed of 40 m/s what is the acceleration

Answer 1

Answer:

8 m/s²

Explanation:

The acceleration of the car can be calculated as follows

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

Where v is the speed and r is the radius. So, replacing v by 40 m/s and r by 200 m, we get;

$a_c=\frac{(40m/s)^2}{200m}=\frac{1600m^2/s^2}{200m}=8m/s^2$

Therefore, the acceleration is 8 m/s²
