A baseball pitcher (m = 81 kg) is initially standing at rest on an extremely slippery, icy surface. He then throws a baseball (m = 0.14 kg) with a horizontal velocity of 49m/s. What is the recoil velocity of the pitcher? (Assume that the positive direction is where the baseball is thrown. Indicate the direction with the sign of your answer.)
