Question

1-kg block rests on a frictionless table and is connected by a light string to
another block of mass 2 kg. The string is passed over a pulley of negligible mass

and friction, with the 2 kg mass hanging vertically. What is the acceleration of the
masses?
a. 5 ms b. 6.53 m/s u. 4.5 m3 d. 20 ms?​

Answer 1

T=ma....(1)
2mg – T = 2ma.... (2)
...
so from 1&2
2mg = 3ma
:. a= 20/3

(m= 1kg & g=10)
