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

8 m/s²

Step-by-step explanation:

The acceleration of the car can be calculated as follows

`a_c=(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=((40m/s)^2)/(200m)=(1600m^2/s^2)/(200m)=8m/s^2`

Therefore, the acceleration is 8 m/s²
