The Earth’s radius is about 6380 km. The

space shuttle is orbiting about 300.1 km above
Earth’s surface.
If the average speed of the space shuttle is
25700 km/h, find the time required for it to
circle Earth.
Answer in units of h

Radius of the orbit R = 6380 + 300.1 km

The circumference of the orbit is
C = 2(Pi)R km

The period of the orbit is then

P = 2(Pi)R/25,700 km/hr

To find the time required for the space shuttle to circle Earth, we can first calculate the circumference of Earth's orbit, and then divide it by the average speed of the space shuttle.

The circumference of a circle is equal to 2π times its radius. So, the circumference of Earth's orbit can be calculated as:

C = 2π * (r + h)

where r is the radius of Earth and h is the altitude of the space shuttle.

Substituting the given values:
r = 6380 km
h = 300.1 km

C = 2π * (6380 + 300.1) km
C ≈ 40,092.4 km

Now, we can divide the circumference of Earth's orbit by the average speed of the space shuttle to find the time required:

Time = C / speed

Substituting the given speed:
speed = 25700 km/h

Time = 40,092.4 km / 25700 km/h
Time ≈ 1.560 hours

Therefore, the time required for the space shuttle to circle Earth is approximately 1.560 hours.

To find the time required for the space shuttle to circle Earth, we can use the formula:

Time = Distance / Speed

First, we need to calculate the distance traveled by the space shuttle during one complete orbit around Earth. We know that the Earth's radius is approximately 6380 km, and the space shuttle is orbiting about 300.1 km above Earth's surface. Therefore, the total distance the space shuttle needs to cover is the circumference of the orbit at 6380 km + 300.1 km above Earth's surface.

Circumference = 2 * π * (Earth's radius + Orbit height)

Circumference = 2 * π * (6380 km + 300.1 km)

Circumference = 2 * π * 6680.1 km

Next, we can determine the time required for the space shuttle to travel this distance by dividing the circumference by its average speed of 25700 km/h.

Time = Circumference / Speed

Time = (2 * π * 6680.1 km) / 25700 km/h

Time ≈ 8.198 hours

Therefore, it would take approximately 8.198 hours for the space shuttle to circle Earth.
