Answer:
C. Both a and b
Explanation:
Firstly, persons and objects in a moving plane as described in this question, are moving at the same speed as the plane even if there is no individual movement of these objects.
However, this question describes a person sitting still in a moving plane. This means that;
- The person is motionless in relation to everything in the plane i.e the person is not moving even if other things in the plane are.
- The person is in motion compared to everything on the ground i.e. the person is moving at the same speed as the plane, hence, in comparison with the ground, the person is moving.
Therefore, options A and B are correct
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
:
