Answer:
2.59 Kg, 3.25 Kg
Explanation:
Acceleration can be found using equation
where s is the release distance, a is acceleration and t is time
Making a the subject of the formula
Substituting 0.28 for s and time for 1 second
Acceleration formula for the Atwood machine is given by
where m1 and m2 are first and second masses respectively
Two situations are possible
When m1>m2
Assuming m1 is 3.7kg which is heavier than m2
Substituting a for and m1 as 2.9Kg and taking acceleration due to gravity as
10.37m2=28.449-1.624
10.37m2=26.825
m2=2.59 Kg
<u>When m1<m2</u>
Then m1=2.9Kg hence
-9.25m2=-28.449-1.624=-30.073
9.25m2=30.073
m2=3.25 Kg
