Objects a and B, of Mass M and 2M Respectively

Multiple Choice

Objects A and B, of mass M and 2M respectively, are each pushed a distance d straight up an inclined plane by a force F parallel to the plane. The coefficient of kinetic friction between each mass and the plane has the same value μk. At the highest point,

A) K_A = Fd = K_B.
B) K_A = (F − μkMg cosθ) d; K_B = (F − 2μkMg cosθ) d.
C) K_A = (F − Mg sinθ) d; K_B = (F − 2Mg sinθ) d.
D) K_A = (F − Mg sinθ − μkMg cosθ) d; K_B = (F − Mg sinθ − μkMg cosθ) d.
E) K_A = (F − Mg sinθ − μkMg cosθ) d; K_B = (F − 2Mg sinθ − 2μkMg cosθ) d.
