In given pully mass system, mass m1=500g, m2=460 g and the pully has a radius of 5 cm. When released from rest, heavier mass falls through 7.50 cm in 5 s. There is no slippage between pulley and string. (i) what is magnitude of acceleration of mass? (ii) what is magnitude of pully's angular acceleration?

​1)    Accelaration = 2*displacement/time*time        [ for s=ut+0.5at^2 ]
      =  0.6 cm/sec
​
2)  Anugular accelaration = R* linear Acceleration
      = 3 cm^2/sec
 
Be careful with the Units , these are not in SI units
