Question

the system shown is in equilibirium when lower spring is cut then waht will be the acceleration of block a just after cutting of the lower spring

Answer 1

Answer:

Given,

Mass=m,2m respectivel

So,

Before the spring is cut,

T+2mg...1

T=mg....2

So,

kx=3mg

After the spring is cut, t=0

a=

2m

kx−2mg

a=

2m

3mg−2mg

a=

2
