Answer:
There are 4845 ways to select four patrols
Step-by-step explanation:
Total number of students in 5 th grade = 20
No. of students selected for patrols = 4
We are supposed to find In how many ways can the four patrols be selected
We will use combination
Formula :
Substitute n = 20 and r = 4
So,the four patrols can be selected in no. of ways =
Hence There are 4845 ways to select four patrols
Using quadratic function concepts, it is found that the minimum initial velocity that must be imparted to the ball is of 10.754 m/s.
<h3>What is the equation of motion?</h3>The equation of motion of an object thrown upwards, considering the effect of the gravity, is given by:
In which:
- v(0) is the initial velocity.
- s(0) is the initial height.
The maximum height obtained is the output of the vertex, which is given by:
In this problem:
- The initial height is of 1 m, hence
.
- A height of 9.8 m is reached when
, hence:
The minimum initial velocity that must be imparted to the ball is of 10.754 m/s.
