On Farth, froghoppers can jump upwand with a takeoff speed of
2.90(m)/(l)
. Suppose some of the insects are taien so an asteroid. If the asteroid is small enough, the froghoppers can jump free of it and escape isto space. Assume an asteroid density of
2.63g_(cm)cm^(3)
. What is the diameter
D_(1)
(in kalometers) of the largest spherical asteroid from which bey could jamp free?
D_(1)=◻,km
Suppose that one of the froghoppers jumped horizontally from a small hill on as asteroid. What would the diameter
D_(2)(iksin)
of the asteroid need to be wo that the insect could go into a circular orbit just above
◻
the narface?
