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.
Part A
With what velocity does the particle strike the earth if it is
released from rest at an altitude y0 = 800 km?

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?

1. Mary is aware of the many ways the body adapts to
training at high altitude. She is a competitive runner and wonders
if training in high-altitude environments will help her performance
at sea level. She wants to implement a "live high, train low"
strategy. How could she achieve this?
a. Live and train at high altitude for one month and then
compete at sea level.
b. Move to a town with higher elevation and train in her
neighborhood.

At what altitude above Earth’s surface would the gravitational
acceleration be 4.9m/s2? Show all the steps in the calculation
starting from first principles. (MEarth = 6.0×1024 kg, REarth =
6.4×106 m.

For the earth, a reasonable estimate of the variation of
pressure with altitude can be made for a gas of molecular weight,
M, assuming the atmosphere is isothermal, the variation of g with
altitude is negligible, and that the atmosphere behaves like an
ideal gas.
(a) Under these assumptions how does the pressure vary with
altitude in terms of the altitude, y, molecular weight of the gas,
M, gas temperature, T, and appropriate constants?
(b) How does the number density...

A 425 kg satellite is in a circular orbit at an altitude of 400
km above the Earth's surface. Because of air friction, the
satellite eventually falls to the Earth's surface, where it hits
the ground with a speed of 2.00 km/s. How much energy was
transformed to internal energy by means of friction?

A ball is shot up from a surface that is 20 m above the surface
with an initial speed of 10 m/s.
1. What is the magnitude of the ball's displacement from the
surface after 3.00 second has elapsed?
2. What max height will the ball reach from the surface of the
earth?
3. How much time elapses between the throwing of the ball and
its reaching to the earth?
4. Calculate the magnitude of the velocity of the ball...
