Determine the escape velocity (minimum speed of an object/body) for planet earth.
Start from the definition of Gravitational force
GM m
F =
and Work
w= S Fdz
where G is the universal gravitational constant, Me is the mass of earth, m is the mass of the object/body, and z is the distance
between Earth and object/body (the same as the radius of earth).
How do you find the escape velocity for objects on the planet Venus?
Calculate the gravitational potential energy of a 8.9-kg mass on the surface of the Earth.
Express your answer using two significant figures.
