A 15 cm tall rock is 1.4 m from the vertex of a curved mirror. The image that the mirror produces is 2.6 m from the vertex of the mirror, inside the mirror. a) What is the focal length of the mirror? b) Is this a converging or a diverging mirror? c) What is the height of the image? A 0.52 m tall potato is 10 m from the vertex of a thin lens. The focal length of the lens is + 8 m. a) What type of lens is this? b) What is the position of the image? c) What is the magnification of the image? d) What is the height of the image?

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.
