Three separated weights (400 N, 294 N, and 98 N) on a frictionless, horizontal table, are all connected by a wire that passes through every weight and then on over a pulley and then fastened to a vertically hanging 500 Newton weight (at a lower level).
Determine the acceleration of the four weights (the three on the table, and the one hanging over the right hand side of the table), and determine theTension1 and Tension2 between the three weights on the horizontal table, and Tension3 over the pulley on the right hand side.
