2. A car with a speed of 61.2 kph [17.00 m/s] is travelling on a straight highway. The driver suddenly applies the brakes right before entering the quarter circular section (radius = 750 m) of the highway at A. It causes the car to slow down at a constant rate. Ten seconds after the car enters the quarter circle section, its speed reduces to 46.8 kph [13.00 m/s]. Which of the following best approximates the magnitude of the acceleration of the car just after entering the curve at A3 V- 17.00 m/s V= 13.00m/s 750m 10 s
