Question

Two blocks of masses 5 kg and 2kg are connected by a massless string as shown in figure a vertical force f is applied on 5 kg block find the value of a few the tension in the string is 40 Newton

Answer 1

m=(5-2)kg=3kg

F=40N

F=ma

40=3×a

a=40/3=13.3m/s

I hope it is right

Answer 2

Answer:

acceleration is 13.3 m/s^2

force =5×13.3=70newton
