Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A ball on the end of a string is whirled around in a horizontal circle of radius 0 . 254 m. The plane of the circle is 1 . 24 m above the ground. The string breaks and the ball lands 2 . 77 m away from the point on the ground directly beneath the ball’s location when the string breaks. The acceleration of gravity is 9 . 8 m / s 2 . Find the centripetal acceleration of the ball during its circular motion. Answer in units of m / s 2 . 002 10.0 points Before throwing a 0 . 808 kg discus, an ath- lete rotates it along a circular path of radius 1 . 47 m. The maximum speed of the discus is 11 . 5 m / s. Determine the magnitude of its maximum radial acceleration. Answer in units of m / s 2 ....
