A 2.00Kg puck on a frictionless horizontal surface on the Earth is constrained to a circular orbit by a 4.00 meter long string attached to a vertical rod.  Assume the string is attached to the rod by a ring that lets it revolve around the rod without friction. The string can withstand up to a 50.0N tension without breaking. If the puck is 0.750Kg, what is the maximum centripetal acceleration the string can withstand?     a. 33.2 m/s2   b. 45.0 m/s2   c. 37.5 m/s2   d. 33.3 m/s2   e. 66.7 m/s2   f. 66.6 m/s2

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
