Part C Since > is a positive quantity, the answer you just obtained implies that w(t) will always have the same sign as ( ($). If the tape is unwinding. both quanitites will be positive. If the tape is being wound back up, both quantities will be negative Now find a ((). the linear acceleration of the end of the tape. Express your answer in terms of o(f), the angular acceleration of the drum: o ($) = ANSWER: a(!) = a(t)r
