Consider a rock traveling straight up and in down in the earth's gravitational eld under the influence of gravity alone near the surface of the earth. Indicate in the chart Whether the quantity is increasing or decreasing in magnitude. For velocity and work indicate the sign. + Trip Up Trip Down v Bk 0 A Eg 0 ET (Total Energy) Work by Force of A Gravity 7. Complete the chart again, but now the rock has an initial velocity of 1.2 X 104 m/s. Distance from Eg E}; velocity ET centre of earth Re 2R6 8R6 Really, really far 8. Plot a graph that shows E., Ek and ET as a function of distance.9. At what distance from the earth Will the rock in this example nally come to rest? 10. The rock is launched from Earth such that it will come to rest when it has travelled an infinite distance from Earth. With What B; was it launched? 12. Complete the chart for escape velocities. Object Radius (111) Mass (kg) Vescape (m/s) Vescape (km/h) Earth 6.3 8X106 5.987(1024 Moon 1.74:3{106 7.3 5x1022 Jupiter 7.15X107 1.907(1027 13. Imagine the earth and all its matter is compressed. a) What size of radius for the earth would give the maximum escape velocity (c= 3.0 X 108)? 14. W" hat is the total energy of an object moving (consult your charts Q#l and 6) a) at its escape velocity? b) slower than its escape velocity? 0) faster than its escape velocity
