A car starts from rest at point O and accelerates uniformly on a straight road for 10 seconds until it reaches point A with a speed of 20 m/s (Stage OA). At point A, the car continues with a constant speed of 20 m/s for 3 minutes (Stage AB). When reaching point B, the brakes are applied and the car decelerates at a constant rate until it stops at point C. The distance travelled by the car from B to C is 20 m (Stage BC). What is the distance covered in stage 2? VA-20 m/s - 20 m/s a) 3600 m b) 3950 m c) 4200 m d) 4450 m e) 4700 m A OA = ? OA 10 s a = ? BC 20 m Bc ? AB = ? AB 180 s a=? O a O e
