One end of a horizontal string is fixed to a wall. A transverse wave pulse in the form of a crest is generated at the other end and moves toward the wall, as shown. Consider the pulse after it has been reflected by the wall. v What is/are correct concerning the reflected pulse? A) The reflected pulse forms a crest. B) The reflected pulse forms a valley. C) The reflected pulse has a greater amplitude than that of the incident pulse. D) The reflected pulse has a greater speed than that of the incident pulse. 1. A and B only 2. A and D only 3. A, B and D only 4. A only 5. B and C only 6. B and D only 7. D only

Abasketball star covers 2.65 m horizontally in a jump to dunk the ball. his motion through space can be modeled precisely as that of a particle at his center of mass. his center of mass is at elevation 1.02 m when he leaves the floor. it reaches a maximum height of 1.90 m above the floor and is at elevation 0.910 m when he touches down again. (a) determine his time of flight (his "hang time"). (b) determine his horizontal velocity at the instant of takeoff. (c) determine his vertical velocity at the instant of takeoff. (d) determine his takeoff angle. (e) for comparison, determine the hang time of a whitetail deer making a jump with center-of-mass elevations yi = 1.20 m, ymax = 2.45 m, and yf = 0.750 m.
