Question

A satellite in orbit around the Earth has a speed of 8 km/s at a given point of its orbit. If the period is 2 h, what is the altitude at that point?

Answer 1

Step-by-step explanation:

Using the formula;

Speed = Distance/Time

Given

Speed = 8km/s

Time = 2hr

Convert 2hr to secs

1hr = 3600secs

2hr = 2(3600)

2hr = 7200secs

Altitude is the distance

From the formula;

Distance = speed × time

Distance = 8×7200

Distance = 57200km

Hence the altitude at this point is 57,200km
