If the speed of the ball after kicking is 48 feet per second then the ball will return on the ground after 3 seconds.
Given that the speed of the ball after kicking is 48 feet per second and the function that represents the height of the ball is .
We are required to find the time that the ball took to travel before returning the ground.
We know that speed is the distance a thing covers in a particular time period.
The height of the ball after t seconds is as follows:
h(t)=
It is at ground at the instants of t.
Hence,
=0
-16t(t-3)=0
We want value of t different of 0, hence :
t-3=0
t=3.
Hence if the speed of the ball after kicking is 48 feet per second then the ball will return on the ground after 3 seconds.

<h2>52</h2>
Step-by-step explanation:
Let the number of fruit trees planted additionally be
Initially it is given that there are trees.
Number of trees after planting additional trees is
Let the yield due to each tree after planting additional trees be
Initially it is given that
Yield due to each tree after planting trees is
=
To maximise yield,we take that value of for which
=
So, and
So,32 additional trees has to be planted to maximise yield.
So,there should be 52 trees in total
1.) 3/5 = 0.6
2.) 4/6 = 2/3 = 0.666667
