Question:
A ball is kicked from the ground with an initial speed of 20 m s−1 at an angle of 30°. Its position after t seconds can be described using the following parametric equations
a. Find the horizontal distance travelled by the ball when it hits the ground. A player wants to head the ball when it is descending between 1.5 m and 2.5 m off the ground.
b. Find the range of time after the ball has been kicked at which the player can head the ball.
c. Find the closest distance from where the ball has been kicked at which the player can head the ball.

I graduated from Maseno University with a Bachelor of Science in Applied Statistics. After graduation, I started tutoring students in mathematics. My experience in mathematics education is extensive and varied. I have taught a wide range of topics, including algebra, geometry, trigonometry, calculus, statistics, probability, and computer science. I have also worked with students of all ages and backgrounds, from elementary school to college.
My teaching method is based on the idea of hands-on learning. I believe that students learn best when they are actively engaged in the learning process, so I focus on giving students the tools they need to explore the material on their own. I also emphasize the importance of practice and review, as these are essential for mastering math concepts.
I have also developed several online and in-person courses on mathematics. My courses are designed to help students learn mathematics in an efficient and comprehensive way, and I use a variety of activities and exercises to ensure that my students are engaged and motivated.
Overall, my passion for mathematics and teaching has allowed me to be a successful tutor and educator in the field. I am confident that my experience will help your students master the mathematics they need to succeed.
