A spherical asteroid has a radius of 545 km and a surface g of 3.0 m/s2.

a.) What is the mass of the asteroid?

b.) What is the potential energy of a 1 kg object on the surface?

c.) What is the minimum speed at which an object* must be thrown upwards from the surface to never come back down?

m/s

d.) If a 1 kg object is thrown directly upwards from the surface with a speed of 1000 m/s,

i.) What is its initial kinetic energy upon launch?

ii.) How high will it go above the asteroid's surface*?

e.) If a 1 kg object is dropped from rest 1000 km above the planet's surface:

i.) What is its initial potential energy when dropped?

ii.) With what speed will the object hit the surface*?

m/s

iii.) When the object has accelerated up to half its eventual impact speed, the object will have fallen to the asteroid's surface.
