ingrid kicks a football with an initial velocity of 12 m/s at an angle 45 relative to the ground. what is the horizontal compone
2 answers:
Let's assume that the coordinate system is defined as positive in the first quadrant.
The system has its origin in the place where Ingrid kicks the football ball.
We have then that the horizontal component is given by:
Rewriting we have:
Rounding the obtained result we have:
Answer:
The horizontal component of the initial velocity to the nearest tenth is:

Static equilibrium means that all forces are equal, so make this easiest you want to break F1 into it's horizontal and vertical components. As there are no other forces acting in the horizontal, we know the horizontal component of F1 is 40N. This allows the vertical component to be found using pythagorus theorem. After finding the vertical and horizontal components, you just have to add the vertical components to find the difference between the up and down.
