A 2 kg cannon ball attached to a rope is rotated about a 1.25 meter radius. If the rope broke when it has a centripetal acceleration of 20, how fast was the cannon ball moving?

Question

Quizplus · Accepted Answer

To find out the velocity of the ball, we use the formula for the centripetal acceleration;
 11ec0fda_9989_6cab_a67f_db5cac67bf95_NR0004_00 a = centripetal acceleration
V = velocity
r = radius of the circular path
Convert the equation:
