Question

A rod of length 1m is held vertically with one end on he floor and left to fall

Answer 1

please complete the question !!!!!!

Answer 2

Answer:

If the complete question is given in explanation if i m right

If mass of bead is m;

mg-µN=ma

Now, N=pseudo force due to acceleration of train, which is equal to 4m Newton.

=> mg-µ(4m)=ma

=> g-4µ=a

=> a=8ms-2

Using, second equation of motion:

1=0.5(8)t2

T=0.5sec

Correct answer is 0.5sec

Explanation:A thin rod of length 1 m is fixed in a vertical position inside a train, which is moving horizontally wit

constant acceleration 4 m/s2. 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
