Question

A man with his middle finger of length 4 cm vertical is sitting in
a car, which is moving horizontally with an acceleration
20 = 5 m/s. A ring can slide on the finger with coefficient of
kinetic friction 0.4. If the ring is released from rest with respect
to man from top of the finger. Find the time after which it will
reach at the lowest point of the finger​
