(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the Atwood machine shown below, m1 = 2.00 kg and m2 = 7.50 kg. The masses of the pulley and string are negligible by comparison. The pulley turns without friction and the string does not stretch. The lighter object is released with a sharp push that sets it into motion at vi = 2.80 m/s downward.

(a) How far will m1 descend below its initial level?

(b) Find the velocity of m1 after 1.80 s.

2. Relevant equations

f= ma

vf^2 = v^2 + 2ad

3. The attempt at a solution

i think for part a u use the equation i put above..but i dont know how to figure out acceleration...but i think its splitted between the two objects
