The kepler mission has recently discovered a number of rocky planets around the stars.Suppose one of these planets has a mass of 7.66 x 10^24 kg and radius of 6743 km.What is the acceleration due to gravity(that is gravitational field) on the surface of t...

An athlete runs at a speed 5 m/s.How fast must he run to have 2.5 times the kinetic energy that he does at that speed?

A 85kg skydiver falls from an altitude of 3.5 X 10^3 M to an altitude of 1.10 X 10^3 m at constant speed.What is her change in potential energy?

Astronauts in orbit appear to be 'weightless'.Suppose an astronaut with a mass of 154 KG including gear is in orbit in the space shuttle, a distance of 222 km above the Earth;s surface.Taking the Earth's radius to be 6371km, and its mass to be 5.97 X 10^2...

Astronomers launch a satellite to explore a nearby asteroid that has come dangerously close to the earth.The satellite begins orbit around the earth,with an orbital radius 6.85 X 10^3 Km, before being moved to an orbit about the asteroid with a period of...

SO A= 222,000Kg?

Im having troubles putting it in so A would equal 767km/h?!!?! and B would equal 345 KG!?

Thats B only? im so lost be more clear please

and B =?

So what would the mass of the asteroid be...?

2.71 ?

Oh my bad thanks for the support !

yeah thats what i meant DO you mind answering the other questions i have up :)

What did we get for B again final answer ?
