What is the approximate tangential speed of an object orbiting Earth with a radius of 1.8 × 108 m and a period of 2.2 × 104 s?

7.7 × 10–4 m/s
5.1 × 104 m/s
7.7 × 104 m/s
5.1 × 105 m/s

is the approximate tangential speed of an object.

Option B

Explanation:

The tangential speed calculate the speed at which an object moves in a circle. The formula calculates the total distance travelled by the object and determines the speed based on how far it travels (distance).

If two objects rotate at the same time, the object moving in a circle with a larger radius has a higher tangential velocity. A larger radius means that the object has travelled a greater distance. Hence the formula for the tangential velocity  is given by

Where,

r - The radius of circular path

ω - The angular velocity

Given data:

r -

t -

By substituting the given values in the above equation, we get

answer: i don't know the answer good luck

explanation:

the body's situation won't change the forces are equal opposit and on the same body
