Elaina Kicks A Soccer Ball With An Initial Velocity Of
1 answer:
By using the motion equations, we conclude that she will make the goal.
<h3>Will she make the goal?</h3>
First, we know that the goal is 20ft away, and the position in x is given by:
Let's find the time in which the ball will travel these 20 ft.
So the horizontal distance is covered in 1.35 seconds, now let's see which is the height of the ball at that time.
The height equation is:
Evaluating in t = 1.35 we get:
And the goal is 5ft tall, so we can conclude that she will make the goal.

Answer:
s = 6 m
Step-by-step explanation:
The value of the velocity v is given as:
m/s
To find s, we have to integrate and apply the initial values of s = o when t = 0:
When t = π/2, s will be:
s = -3cos(2 * π/2) + 3
s = -3cos(π) + 3
s = -3(-1) + 3
s = 3 + 3
s = 6 m

so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2
answer is 336 m^2
