Mass of ball m = 7.5 kg Radius of ball r = 9.0 cm = 0.09 m Distance rolled s = 10 m Speed V = 4.3 m/s Angular Displacement D = Distance rolled / Radius of ball = 10 / 0.09 = 111.1 rad Angular Velocity w = Speed / Radius of ball = 4.3 / 0.09 = 47.77 rad / s Radial acceleration = r x w^2 = 0.09 x 47.77^2 = 205.44 m/s^2 Tangential acceleration = 0 as there was no deviation or skidding of the ball and the travel was inward.
