The car moves along a road curve with a radius of 100 m at a speed of 54 km / h, what is the magnitude of its centripetal acceleration.
Centripetal acceleration is calculated using the formula:
a = V² / R,
where V is the speed, R is the radius of the rounding.
V = 54 km / h = 54000 m / 3600 s = 15 m / s;
Substitute the values from the condition:
a = (15² m² / s²) / 100 m = (225/100) m / s² = 2.25 m / s².
Answer: 2.25 m / s².
