A pully of 5cm radius with a belt, on a motor, is turning at 30rev/s and slows down uniformly to 20rev/s in 2s, find the angular and radial acceleration of the motor?

answer: i don't know the answer good luck

explanation:

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

what is the actual question though?

not too sure thinking all accelerations are pointed down
