In the lab setup above, block 1 is being pulled across a smooth surface by a light string connected across a pulley to a falling block 2. The pulley has negligible mass and friction. Students measure the mass of each block, the distance from A to B , and the speeds of the block on the surface at points A and B . Which of the following hypotheses can be tested with this setupAs block 1 moves from point A to point B, the work done by the tension on block 1 is equal to the kinetic energy of block 1 at point B. As block 1 moves from point A to point B, the work done by the tension on block 1 is equal to the kinetic energy of the two-block system when block 1 is at point B. As block 1 moves from point A to point B , the work done by gravity on block 2 is equal to the kinetic energy of block 1 at point B. As block 1 moves from point A to point B, the work done by gravity on block 2 is equal to the change in the kinetic energy of the two-block system. As block 1 moves from point A to point B, the work done by the tension on block 2 is equal to the kinetic energy of block 2 when block I has reached point B.

Abatter hits a 0.140-kg baseball that was approaching him at 30 m/s and, as a result, the ball leaves the bat at 40 m/s in the reverse of its original direction. the ball remains in contact with the bat for 2.0 ms. what is the magnitude of the average force exerted by the bat on the ball?
