Step-by-step explanation:
Given two vectors a and b,we are rquired to find the angle between them.
a=(8,7);b=(7,0).
Angle between two vectors can be found by dot product of them.
If a and b are two vectors then the dot product of them is given by|a||b|cos(α).
Where α is the angle between the vectors a and b.
Now . and
=56.
Now cosα= so α= cosine inverse of that.
∴α=

Chech the picture below.
if the person kicked it from the ground, that means its initial height is 0.
it reaches its maximum height at the y-coordinate of its vertex, and it will hit the ground when y = 0, as you see in the picture.
now let's find the y-coordinate of its vertex
when will it hit the ground?
