Question

The moon Umbriel orbits Uranus (mass = 8.68 x 1025 kg) at a distance of 2.66 x 108 m. What is Umbriel's orbital speed?

Answer 1

Answer: 4665

Explanation: I got it right after on acellus

Answer 2

the orbital speed of umbriel is 16,800 km/h

Step-by-step explanation:

The computation of the orbital speed is shown below

According to the question the Data provided in the question

Uranus mass = 8.68 × 10^25 kg

Distance = 2.66 × 10^8 m

Based on the above information, the orbital speed of Umbriel is

`V = \sqrt{(GM)/(R) } \\\\ = \sqrt{(((6.673e-11)(8.68e25))/(2.66e8) }`

V = 4666 m/s

= 16,800 km/h

Hence, the orbital speed of umbriel is 16,800 km/h

Therefore it can be calculated by applying the above formula
