A girls sits on a tire that is attached to an overhanging tree limb by a rope. The girl's father pushes her so that her centripetal acceleartion is 3.8 m/s2. If the length of the rope is 3.3 m,
a) what is the girl's tangential speed?
b) If the magnitude of the force that maintains her circular motion is 88 N, what is the girl's mass?
