Transcribed Image Text:12. A small ball is attached to the lower end of a 0.800-m-long string, and the other end of the
string is tied to a horizontal rod. The string makes a constant angle of 37.0° with the vertical as
the ball moves at a constant speed in a horizontal circle. If it takes the ball 0.600 s to complete
one revolution, what is the magnitude of the radial acceleration of the ball?
A) 52.8 m/s²
B) 39.1 m/s²
C) 60.6 m/s²
D) 47.3 m/s²
E) 22.8 m/s²
