Question

 

 

A 5.00 kg object placed on a frictionless, horizontal table is connected to a string that passes over a pulley and then is fastened to a hanging 9.00 kg object, as shown in the figure. Find the magnitude of the acceleration of the two objects and the tension in the string

acceleration of 5.00 kg object

acceleration of 9.00 kg object

 

 

 

Answer 1

To find acceleration, use

a = g M / (M + m)    where M = 9 kg, m = 5 kg, g = 9.81 m/s²

 

To find tension T, use

T = m a
