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?

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

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 = 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

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
