Question

Answer 1

Answer #1

number of revolutions per second = 4

radius of circle = 0.02 m

time period = 1/4 = 0.25 seconds

angular speed becomes w= (2xpi)/T = 25.12 radians/second

Angular acceleration is = rw^2 = 25.12²*0.020 = 13 m/s²

Answer is [C]

Hope you will find the answer useful. Please rate. Cheers.
