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.

A super-roach Bob is moving at a constant speed in a circular path on the frying pan with a radius of 20.1 cm. Why? Because it’s hot. I must also mention here that I have just found out from a biologist friend of mine that when the roaches run, they raise their front and run mainly on the back legs, “hydroplaning” themselves forward. Scary, isn’t it? But, if Bob makes two and a half revolutions each second, what is the...
