Which of the following is/are formula(s) for tangential acceleration?

Question

Quizplus · Accepted Answer

Tangential acceleration is the rate of change of tangential velocity. The formula for tangential acceleration is a_t = (v_t-v_t)/t, where v_t is the final tangential velocity, v_t is the initial tangential velocity, and t is the time interval. Another formula for tangential acceleration is a_t = ra, where r is the radius of the circular path and a is the centripetal acceleration.
