Answer:
South-West direction
Explanation:
Let
be velocity of the plane relative to the air,
be velocity of the air relative to the ground,
is the velocity of the plane relative to the ground
therefore,

From the triangle attached, the angle characteristics to the direction of relative velocity of the plane can be found



South-West direction
Answer:
I've combined both answers on a single graph.
Explanation:
Answer:
A
Explanation:
In section A, she is moving in constant speed because there's a flat line which indicates speed remained same as time passed. In section c, there's a flat line but look at y axis for this one, it is 0 which means there's no speed during this part. B and D have varying speeds as there is a change in y axis variables as time passes.
The second one (4.1 kg ball)
This is because the mxv is greater than the other one.
For the 4.1kg ball, the force it’s moving on is 4.92N
As for the 3.2kg ball, it’s moving with a force of 0.9N. Much less than the other one.
