Answer 1

Answer:

v = 0.0251 km/h

Explanation:

Given that,

The average distance from its center of mass of 1000 meters.

The time taken is  24 hours and 57 minutes to complete one orbit

We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,

$v=\dfrac{2\pi r}{t}$

Putting all the values,

$v=\dfrac{2\pi \times 100}{24\ hours\ and\ 57\ minutes}\\\\v=\dfrac{2\pi \times 100}{(86400+3420)}\\\\v=0.00699\ m/s$

or

v = 0.0251 km/h

So, the average orbital velocity is 0.0251 km/h.
