A drum rotates around its central axis at an angular velocity of 18.9 rad/s. If the drum then slows at a constant rate of 3.73 rad/s2, (a) how much time does it take and (b) through what angle does it rotate in coming to rest?

Answer with Explanation:

We are given that

Initial angular velocity,

Angular acceleration,

a.We have to find the time taken by drum in coming to rest.

We know that

Using the formula

b.

Using the formula

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
