Question

the vertical distance between the masses is 20/3m at t=0 .the distance becomes 0 at t = ? { g=10}. 1)2. 2),√2 3),4 4)√6​

Answer 1

Answer:

a) 2s

Explanation:

For these questions remember the condition for equilibrium

that is 1. balance the vertical forces 2. balance the horizontal forces and 3. balance all the moments.

In this question there are no horizontal forces and no moment. so we only have to deal with the vertical forces.
