Number of Turns/Circular Motion

[smr101]

Having problems with (b)(iiI).

I've tried using the kinetic energy value = work done and dividing that by torque.

I've also tried used the other circular motion formulas but haven't had any success.

Attempt:

Wd = θ x T

Ek(from b ii) = Wd

θ = 2278.29/0.6
= 3797 turns

I've added what I tried.

He, this is a duplicate thread !

I'm asking about a different question here, previous one was in regards to (b) (i), this is (b)(iii).

θ = 2278.29/0.6 = 3797 turns

Two errors..

1)Typo.. 2278.29 should be 2778.29
2) Check the units of angular displacement θ. (Hint: it's not turns)
