In the image shown, two blocks hang on a pulley. Assume that m1 is the more massive block, and that the pulley is massless and frictionless.
Take the initial case to be the instant just after m1 is released from rest, and the final case to be the instant just before m2 hits the pulley. Compare the magnitudes of the quantities below at those times.
The initial tension on m1 versus the final tension on m1.
The initial tension on m1 versus the force of gravity on m2.
The initial tension on m2 versus the final tension on m1.
The initial tension on m2 versus the force of gravity on m2
T-m_2 = m_2*a
The Attempt at a Solution
I tried to figure out the initial tension on m_1. I thought it is m_2*g but this is wrong. I guess m_2*g is the tension of the whole string. Am I right?
This initial mistake caused the other.
