HW Ch. 2 Motion in One Dimension Chapter 2: Motion in One Dimension Conceptual problems 2.C.5 (5.00) A diver is standing on a diving board that is 15 meters above the surface of the water. He jumps 0.50 meters straight up into the air, dives into the water and goes 3.0 meters underwater before returning to the surface. (a) Assume that "up" is the positive direction. What is the vertical displacement of the diver from when he is standing on the diving board to when he emerges from underwater? (b) Now assume that "down" is the positive direction. Determine the displacement, as before. (a) (0/6 submissions used) m (b) (0/6 submissions used) m 2.C.14 (5.00) A truck full of corn is parked at x = 0 and is pointed in the negative direction. If the driver puts it into reverse and holds down on the accelerator, will the following quantities be positive, zero, or negative after one second? (a) position, (b) velocity, (c) acceleration. (a) PositiveNegativeZero (0/1 submissions used) (b) PositiveNegativeZero (0/1 submissions used) (c) PositiveNegativeZero (0/1 submissions used) 2.C.15 (5.00) David is driving a minivan to work, and he is stopped at a red light. The light turns green and David drives to the next red light, where he stops again. Is David's average acceleration from light to light positive, negative, or zero? PositiveNegativeZero (0/1 submissions used) 2.C.17 (5.00) A football is thrown vertically up in the air at 10 m/s. If it is later caught at the same spot it was thrown from, will the speed be greater than, less than, or the same as when it was thrown? Ignore air resistance.

He walks home after school. If the front of Brian's house is the origin, (a) what is the position of the school, (b) what is his displacement on the walk home, and (c) what is his displacement due to the combination of the bus journey and his walk home?

They traveled 60.0 miles due south from their first concert to Huntsville. If Huntsville is 80.0 miles due north of Houston, what is their displacement from the first concert to Houston? Use the convention that north is positive, and south is negative. (0/6 submissions used)
