Answer #1

Gravitational constant = G = 6.67 x 10-11 N.m2/kg2

Density of the asteroid = = 2410 kg/m3

Diameter of the asteroid = D = 265 km = 265000 m

Radius of the asteroid = R = D/2 = 265000/2 = 132500 m

Volume of the asteroid = V

V = 9.744 x 1015 m3

Mass of the asteroid = M

M = V

M = (2410)(9.744x1015)

M = 2.348 x 1019 kg

Escape velocity from the asteroid = Ve

Ve = 153.75 m/s

A) Escape speed from the asteroid = 153.75 m/s

On Earth, froghoppers can jump upward with a takeoff speed of 2.8 m/s. Suppose you took some of the insects to an asteroid. If it is small enough, they can jump free of it and escape into space. Assume a typical asteroid density of 2.2 g/cm3. Suppose that one of the froghoppers jumped horizontally from a small hill on an asteroid. a) What is the diameter (in kilometers) of the largest spherical asteroid from which they could jump free? (Express...

The escape speed from an object is v2 = 2GM/R, where M is the mass of the object, R is the object's starting radius, and G is the gravitational constant 6.67 × 10-11 m3 kg-1 s-2. What is the approximate escape speed, in km/s, from the Solar System starting from an orbit at 0.6 AU? In this case, the mass of the Sun, 2.2e+30 kg, can be used as the mass of the Solar system.
