Acertain spherical asteroid has a mass of 3.5 × 10^16 kg and a radius of 8.8 km. what is the minimum speed needed to escape from the surface of this asteroid? a) 730 m/s b) 16 m/s c) 23 m/s d) 520 m/s

To solve this problem we will use the Newtonian theory that describes the escape velocity of a body of a planet as:

Where,

G = Gravitational Universal Constant

M = Mass of Asteroid

r = Radius

Our values are given as,

Replacing we have,

Therefore the correct answer is C.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
