A car makes a turn with a 20m radius, the car's speed is 10m.s. what is the centripetal acceleration?
To find the centripetal acceleration of a car making a turn, we can use the formula:
Centripetal acceleration (aᵖ) = (Velocity²) / (Radius)
In this case, the car's speed is given as 10 m/s and the radius of the turn is 20 m. Putting these values into the formula:
aᵖ = (10 m/s)² / (20 m)
To solve the equation, we square the velocity:
aᵖ = 100 m²/s² / 20 m
Next, we divide the squared velocity by the radius:
aᵖ = 5 m/s²
Therefore, the centripetal acceleration of the car making the turn is 5 m/s².
