An Atwood machine is set up like the figure which is given below.
If m1=4.5kg and m2=6.0kg. What is the acceleration of the system when the masses are released? (Take the value of g=10ms−2)

Solution
The acceleration of the blocks in the case of Atwood machine is calculated as: a=(m2−m1)gm1+m2 As (m2>m1)
where, m1 and m2 is the mass of block 1 and 2 and g is the acceleration due to gravity.
Here, m1=4.5kg and m2=6.0kg
Therefore, a=(6−4.5)×104.5+6=107ms−2
