system of particles

Two particles of masses 3 kg and 5 kg are connected by a light inextensible string, of length 4 m, passing over a light smooth peg of negligible radius. The 5 kg mass rests on a smooth horizontal table. The peg is 2.5 m directly above the 5 kg mass. The 3 kg mass is held next to the peg and is allowed to fall vertically a distance 1.5 m before the string becomes taut. does any one know what this question looks like i cant even imagine it

This is extremely difficult to answer without drawing it out, in which case I have done the first part of your homework for you.

 

Try re-arranging the instructions.

 

There is a 5kg mass resting on a table. A 3kg mass sits directly above it. The latter is adjacent to a peg (which must therefore also be immediately above the 5kg mass on the table. Can you take it from there?
