A {1.501 insect rests on a comcact disc at a distance of 4.0 cm from the centre. The disc's rate of rotation
varies from 3.5 Hz to so He in order to maintain a constant data sampling rate. [4 marks] 1What are the
insect's minimum and maximum centripetal accelerations dun'ng its rotation around the disc?
Minimum Centripetal Acceleration = 1934.44 cm/s^2
Maximum Centripetal Acceleration = 10 106.47 cm/s^2
