Find out the speed, magnitude and direction of acceleration of the ball moving in vertical circle.

A 2.00 kg ball swings in a vertical circle on the end of an 80 cm long string. The tension in the string is 20 N while its angle from the highest point on the circle is q= 300

1. What is the ball's speed when q= 300 ? v= ________m/s

2. What is the magnitude of the ball's acceleration when q= 300 ? a= _______m/s2

3. What is the direction of the ball's acceleration when q= 300 ? Give the direction as an angle from the r-axis. f=__________0
