Two cats are sitting side-by-side on a fence when they’re startled bya dog. The cats jump off the fence with equal speeds, but differentinitial angles relative to the horizontal. Cat 1 jumps at an angle of45° above the horizontal; cat 2 jumps at an angle of 45° below thehorizontal. Is the landing speed of cat 1 greater than, less than, orequal to the landing speed of cat 2?
Two stones A and B are thrown simultaneously from the two buildings of height
