A 3.50 kg block on a smooth tabletop is attached by a string to a hanging block of mass 2.80 kg. The blocks are released from rest and allowed to move freely.
1-Is the tension in the string greater than, less than, or equal to the weight of the hanging mass?
2-Find the acceleration of the blocks.
3-Find the tension in the string.
less than, the block is falling, so has to weigh less.
2.80=(2.80+3.5)a solve for a
