Final answer:
The magnitude of the centripetal acceleration of the car is 5 m/s^2.
Step-by-step explanation:
Centripetal acceleration is the acceleration experienced by an object moving in a circular path. It can be calculated using the formula: ac = v^2 / r, where ac is the centripetal acceleration, v is the velocity of the car, and r is the radius of the corner.
First, we need to convert the speed of the car from km/hr to m/s. 36 km/hr is equal to 10 m/s. The radius of the corner is given as 20 m. Plugging these values into the formula, we get: ac = (10 m/s)^2 / 20 m = 5 m/s^2.
Therefore, the magnitude of the centripetal acceleration of the car is 5 m/s^2.
