A drum rotates around its central axis at an angular velocity of 19.8 rad/s. If the drum then slows at a constant rate of 3.02 rad/s2, (a) how much time does it take and (b) through what angle does it rotate in coming to rest

a) Time taken =6.39 s

b) Angle of rotation while coming to rest = 188.17 rad

Explanation:

Initial angular velocity of the drum

Angular acceleration of the drum

a.) We know that

b.) we know that

a is the best answer your welcome

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
