An object moves with a constant speed of 30 m/s on a circular track of radius 150 m.What is the acceleration of the object? A)0 m/s² B)0.17 m/s² C)5.0 m/s² D)6.0 m/s²

Question

Quizplus · Accepted Answer

Acceleration is given by a=v^2/r, where v is the speed of the object and r is the radius of the circular track. In this case, v = 30 m/s and r = 150 m, so a = (30 m/s)^2 / 150 m = 6.0 m/s^2.
