Movement can be without change in positions. As only a part of it can be made to move. If you move there is a motion and if there is a motion there is a movement so they're same thing. In motion whole of body moves, but in movements only the parts of body moves.
Answer:
9.4
Explanation:
magnitude is the sum of the squares.

If you are given horizontal and vertical components, treat those as the rise and run of a triangle, the rise of 8 with a run of 5 and you want to find the hypotenuse.
How do you find the long side of a triangle?
Answer: Third option
F = 250w
Explanation:
The impulse can be written as the product of force for the time interval in which it is applied.

You can also write impulse I as the change of the linear momentum of the ball

So:

We want to find the force applied to the ball. We know that
milliseconds = 0.03 seconds
The initial velocity
is zero.
The final speed 
So


We must express the result of the force in terms of the weight of the ball.
We divide the expression between the acceleration of gravity


The answer is the third option
