An air hockey puck is attached to a string with a length of .45 m and is set in a circular motion with a period of 2.0 s. If the tension in the string is .789 N and we assume there is no friction:

A. What is the tangential speed of the puck?

B. What is the centripetal acceleration of the puck?

C. What is the mass of the new puck?

D. What would be the new tension in the string if the tangential speed was twice as fast?
