Question

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)

Answer 1

Answer:

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
