what is the gravitational acceleration ON the surface
of Mars, if its mass is 6.39∙1023 kg, and the
radius is 3.39∙106 m? (b) How many times is this acceleration
greater than the gravitational
acceleration at the location OF Mars, provided by the Sun (mass of
the Sun is 1.99∙1030 kg, and the
radius of Mars’ orbit is 2.28∙1011 m)? (c) If it takes Mars 687
days to complete one revolution around
the Sun, calculate Mars’ tangential and the angular velocity

As a body is projected to a high altitude above the earths surface,
the variation of the acceleration of gravity with respect to
altitude y must be taken into account. Neglecting air resistance,
this acceleration is determined from the formula a=?g0[R2/(R+y)2],
where g0 = 9.81 m/s2 is the constant gravitational acceleration at
sea level, R = 6356 km is the radius of the earth, and the positive
direction is measured upward.

A planet has the same density as Earth but has a surface
gravitational acceleration of nine times that of
the Earth (a person would instantly black out if placed on the
surface). What is the escape velocity from the planet? If
the planet was in an orbit of 1 AU from a 1 M⊙ star, what is
the maximum distance that a moon could orbit the planet?

A satellite is launched into an orbit at an altitude 200 km
above the surface. Onboard is an exquisitely sensitive atomic clock
that is synchronized with an identical clock on Earth. After
orbiting for one year, the satellite is captured, returned to
Earth, and the clocks compared. What will be the shift in time
between the two clocks?
