a.
Find the escape velocity of the weather satellite.
a.
Answer to Problem 73E
Explanation of Solution
Given information:
A weather satellite in a
Find the escape velocity of the weather satellite.
Calculation:
To find the escape velocity of the weather satellite. It is given
We know the escape velocity is
The escape velocity of the weather satellite.
Hence, the escape velocity of the weather satellite is
b.
Find the escape velocity of the weather satellite.
b.
Answer to Problem 73E
Explanation of Solution
Given information:
A weather satellite in a
Find an equation of the parabolic path of the weather satellite. (Assume that the radius of Earth is 4000 miles.)
Calculation:
Consider the figure,
Assume that the radius of Earth is
The path of the satellite is parabola with vertical axis,
The standard equation of parabola with vertical axis is,
Now the vertex is given as
Now,
Now focus is the centre of the earth has points
Hence, the equation of the parabolic path is
