5. A top WNBA player can jump about .7 meters off the ground. If her mass is 50 kg, what force must she exert against the ground? Assume she crouches a distance of .2 metes prior to jumping, and thus the upward force has this distance to act before leaving the ground. 6.

C7 9.) If the orbit is elliptical, rather than circular, what can be said about the work done by the Sun on Earth? a.) It does not matter whether the orbit is circular or elliptical, no work is done. b.) The work the Sun does on Earth causes the tides. c.) Whether the orbit is circular or elliptical, work must be done to propel Earth around the Sun. d.) If the orbit is elliptical, work is done to speed up or to slow down Earth, depending on its location in orbit. e.) The work the Sun does on Earth accounts for Earth's changes of season.
