N EllTl'E FBI 1. A bird flying over your head drops a walnut that it was carrying in its beak. If the bird is flying horizontally at an altitude of 23.5 m, and the walnut travels a horizontal distance of 12.5 Hi, how fast was the bird ying? 2. One end of a spring is attached to a solid wall while the other end just reaches to the edge of a horizontal, frictionless tabletop, which is 88.5 cm above the deck. A 2.00 kg block is placed against the end of the spring and pushed toward the wall until the spring has been compressed a distance of 15.0 cm. The block is released, slides across the table, and strikes the floor a horizontal distance of 1.20 m from the edge of the table. Air resistance is negligible. Find (a) the time elapsed from the instant the block leaves the table to the instant it strikes the floor, (b) The horizontal component of the velocity of the block just before it hits the floor, (c) The work done on the block by the spring, and (d) The spring constant
