"By means of a rope, whose mass is negligible, two blocks (mass: 11kg and 44 kg) are suspended over a pulley. The pulley can be treated as a uniform solid cylindrical disk. The downward acceleration of the 44 kg block is observed to be exactly one half the acceleration d...

Since there are no non-conservative forces involved in this scenario, you can use the principle of the conservation of momentum. Set up the momentum of the baseball player equal to the momentum of the baseball: (75kg)(vB)=(0.145kg)(40m/s). The velocity of the baseball player ...
