Question

find the acceleration of Tension in all strings and acceleration of the system.​

Answer 1

Answer:

Let 5 kg mass moving down with acceleration a

5g−T=5a----------(1)

T−20gsin30

o

=20a

T−20g

1

=20a---------(2)

⇒5g−

2

20g

=25a

⇒−5 g=25 a

⇒a=−

5

g

Negative sign indicates 5 kg mass will move upward with an acceleration a=

5

g
