Two objects are connected by a string of length 4.8 m and negligible mass.
the 10 kg block is placed
on a smooth table top,
aud the 7 kg block hangs over the edge of the table. The 7 kg block is then released
from restata distauce of 1.2 m above the floor at time t =0. (the distance from the 10 kg block to the end of the table is 3.6 m)

The acceleration of gravity is 9.8 m/s2. What is the 7 kg block acceleration as it decends
