Question: A 2.0 kg ball swings in a vertical circle on the end of an 80cm long string. The tension in the string is 20N when its angle from the highest point on the circle is q= 300

[A] What is the magnitude of the ball's acceleration when q= 300? a= _______m/s2
[B] What is the ball's speed when q= 300? v= ________m/s
[C] What is the direction of the ball's acceleration when q= 300? Give the direction as an angle from the r-axis. f=__________0
