Special air bags are used to protect scientific equipment when a rover lands on the surface of mars. on earth, the function approximates an object's downward speed in feet per second as the object hits the ground after bouncing x ft in height. the corresponding function for mars is compressed vertically by a factor of about 2/3. estimate to the nearest tenth how fast a rover will hit mars' surface after a bounce of 15 ft in height.
a) 20.7 ft/s
b) 25.3 ft/s
c) 7.3 ft/s
d) 46.5 ft/s
