Solve the all parts of following question given below:
Question: A 7.2-cm-diameter gear rotates with angular velocity (2.0 + 1/2t2) rad/s, where t is in seconds. At t = 9.0s,
Part A: Find the gear's angular acceleration?
Part B: Find the tangential acceleration of a tooth on the gear?
I need help to determine the tangential acceleration of a tooth on the gear.
