Answer:
<u><em>note:</em></u>
<u><em>solution is attached due to error in mathematical equation. please find the attachment</em></u>
Time = (distance) / (speed)
<em></em>
Time = (450 km) / (100 m/s)
Time = (450,000 m) / (100 m/s)
Time = <em>4500 seconds </em>(that's 75 minutes)
Note:
This is about HALF the speed of the passenger jet you fly in when you go to visit Grandma for Christmas.
If the International Space Station flew at this speed, it would immediately go ker-PLUNK into the ocean.
The speed of the International Space Station in its orbit is more like 3,100 m/s, not 100 m/s.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
As we know that force on the passenger while moving in circle is given as
now variation in force is given as
here speed is constant
Part b)
Now if the variation in force is required such that r is constant then we will have
so we have
Part c)
As we know that time period of the circular motion is given as
so here if radius is constant then variation in time period is given as
F=W=mg
12N(given)= m*9.8
m= 1.22 kg
