Question

0. What is the maximum compression in the spring,
if the lower block is shifted to rightward with
acceleration a? (Given that all surfaces are smooth
as shown)
000000000-m​

Answer 1

Answer:

If you see from the lower block frame of reference. A pseudo force 'ma' acts on the block.

This 'ma' acts backwards and compresses spring by 'x'

Under maximum compression the forces are balanced

kx = ma

Therefore

x = ma/k

Max compression = ma/k

Answer 2

Answer2ma/k
