Block B is on a ramp inclined at a 45 degree angle; it is connected to block A via a string that runs over a pulley, so that A hangs vertically. You may assume that the string remains taut and does not stretch or break, and that the masses of the strings and pulley are negligible compared to the masses of A and B. You may also neglect friction throughout this problem. Block B has three times the mass of block A. At the time we are considering, block B is sliding up the ramp and slowing down. A.) draw vectors to indicate the accelerations of blocks A and B, with the correct directions and magnitude. After drawing your vectors, explain how you figured our the correct directions and magnitudes.
