Question

Two stones of masses 10kg and 15kg are attached by a rubber cord. The cord is stretched.
placed on a horizontal smooth table. If the first stone moves with an acceleration of 3m/sec2
the acceleration of the second is:
(A) zero
(B) 4.5 m/s2 (C) 5.4 m/s2 (D) 2 m/s​

Answer 1

Answer:

plz make me brainliest plz

Answer 2

Answer:

2m/s^2

Explanation:

The force on 10kg = ma= 10*3= 30N

This force will act on 15kg object as they both are connected by the cord

so its acceleration = F/m = 30/15  = 2m/s^2
