Iserve a volleyball at a 730 angle with the horizontal, and an initial speed of 5.6 feet per second. what is the component form of the velocity? round to three decimal places out from the zero.

Velocity = 1.637i + 5.355j

Step-by-step explanation:

If you serve a volleyball at 73° angle with the horizontal and an initial speed of 5.6 feet per second.

Then horizontal component of the velocity = 5.6×cos73°i = 1.637i

and vertical component of the velocity = 5.6×sin73°j = 5.355j

Finally the component form of the velocity will be = 1.637i + 5.355j

i can't see the picture : /

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
