Problem

A thin rod of length 1 m is fixed in a vertical position inside a train, which is moving horizontally with constant acceleration

4 \text{ m/s}^2

. A bead can slide on the rod, and friction coefficient between them is

1/2

. If the bead is released from rest at the top of the rod, find the time when it will reach at the bottom. (

g=10\text{m/s}^2

)
