A m1 = 4.00 kg block on a smooth tabletop is attached by a string to a hanging block of mass m2 = 2.50 kg, as shown in Figure 6-29. The blocks are released from rest and allowed to move freely. So m1 is on top of a table and m2 is hanging down from a string. What is acceleration and tension?

Assuming no friction, take T to be the tension in the string and a as the acceleration of both blocks
A FBD of the hanging mass
2.5*9.81-T=2.5*a
and the one on the table
4*a=T
solve for a and T
2.5*9.81-4*a=2.5*a
a=3.77 m/s^2
T=15.1 N
the tension is less than the weight of the hanging mass
The weight of the hanging mass is 24.5 N
