Answer:
The height reached by the material on Earth is 91 km.
Explanation:
Given that,
Mass
Radius = 1821 km
Height
Suppose we need to find that how high would this material go on earth if it were ejected with the same speed as on Io?
We need to calculate the acceleration due to gravity on Io
Using formula of gravity
Put the value into the formula
Let v be the speed at which the material is ejected.
We need to calculate the height
Using the formula of height
Using ratio of height of earth and height of Io
Put the value into the formula
Hence, The height reached by the material on Earth is 91 km.
Answer:
Explanation:
you mean deceleration right ? because the acceleration is 250m/s
