1) A soccer ball is kicked across a field at an angle of 44° with an initial speed of 21 m/s. i) Write a set of parametric equations for the motion of the soccer ball.
ii) Determine how long the soccer ball was in the air.
iii) Determine how far the soccer ball traveled in the air.
iv) Determine when the soccer ball reached its maximum height.
y Determine the maximum height reached by the soccer ball.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
