A car with a speed of 54 km / h moves along a curve with a radius of 250 m. Find the centripetal acceleration of the car.
V = 54 km / h = 15 m / s.
R = 250 m.
a -?
The centripetal acceleration of the car a is determined by the formula: a = V ^ 2 / R.
a = (15 m / s) ^ 2/250 m = 0.9 m / s2.
Answer: the car is moving with centripetal acceleration a = 0.9 m / s2.
