A race car traveling at a constant speed of 50 m/s drives around a circular track that is 500 m in diameter.What is the magnitude of the acceleration of the car? A)0 m/s² B)1.0 m/s² C)10 m/s² D)0.63 m/s² E)2.2 m/s²

Question

Quizplus · Accepted Answer

The acceleration of an object moving in a circle at constant speed is given by the formula a = v²/r, where v is the speed and r is the radius of the circle. Here, v = 50 m/s and r = 250 m (since the diameter is 500 m). So, a = (50)² / 250 = 10 m/s².
