hi, if anyone could give me any sort of help on how to solve this problem i would greatly appreciate it. thank you.

A 2.66 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 8.39 kg object. Find the magnitude of the acceleration of the two objects.

Let M1 be the mass on the table and M2 be the mass hanging from the pulley. Let T be the tension force in the cable that connects them. Both masses accelerate at the same rate a, but in different directions.

Solve this pair of equations. There are two unknowns, a and T.

M1 g - T = M1 a
T = M2 a

Add the two equations to elimimate T
M1 g = (M1 + M2) a
Solve for a.
