[2 pts.] Conceptual question. Two identical blocks are pushed up frictionless inclines as shown. Consider the portion of the motion of block 1 during which it moves a distance Ly, and the portion of the motion of block 2 during which it moves a distance L. Each block is displaced the same vertical distance Z. The hand pushes parallel to the incline with same msgnitude of force Fow in both cases. Block 2 moves at a decreasing speed. a. b. Is the absolute value of the work done by the hand on block 2 greater than, less than or equal to the absolute value of the work done by hand on block 1? Explain. Is the absolute value of the work done by the gravitational force on block 2 greater than, less than, or equal to the work done by the gravitational force on block 1? Explain. Use the work-kinetic energy theorem to determine whether the speed of block 1 increases, decreases, or remains constant as it moves the distance shown (LI). (Can it be determined based on the information provided?) Explain. c.
