Answer:
The skier's change in velocity is 7.69 meters per second.
Explanation:
The Newton's second law tells force is equal to the change on the linear momentum of a body:
If we approximate the differential 
to 
:
Using that linear momentum is mass times velocity:
Solving for 
:
For this task we need to use Kepler's third law:
T = 2*pi*
where T is orbital period in seconds, r is Venus's semi-major axis, G is gravitational constant and M is mass of the sun.
Distance from earth to sun is 1AU so if we know earths period and distance from the sun we can calculate Venus period.
Te-earths period
Tv-venus period
From the text we know that Re/Rv = 1/0.723
Which means that:
Tv = 0.614 Te
There could as smaller objects have more inertia. Mass is a measure of an objects in Harsha. Objects with greater mass have a greater in Inertia yet it’s still maintains the same amount of inertia as usual. It still has the same tendency to resist changes in its state of motion. So yes it is possible that there could ever be a situation where a small sports car would have more inertia than a big bus. :)
the answer is true because they're so close together that they can't move they can't slide past each other or anything
