A ball on the end of a string is whirled around in a horizontal circle of radius 0.471 m. The plane of the circle is 1.37 m above the ground. The string breaks and the ball lands 2.85 m away from the point on the ground directly beneath the ball's location when the string breaks. bThe acceleration of gravity is 9.8 m/s^2
Find the centripetal acceleration of the ball during its circular motion.
A car at the Indianapolis-500 accelerates uniformly from the pit area, going from rest to 340 km/h in a semicircular arc with a radius of 194 m. Determine the radial acceleration of the car at this time
