Activity 1: How far can a soccer player kick a soccer ball downfield? Through the application of a linear function and a quadraticfunction and ignoring wind and air resistance one can describe thepath of a soccer ball. These functions depend on two elements thatare within the control of the player: velocity of the kick (v k )and angle of the kick (?). A skilled high school soccer player cankick a soccer ball at speeds up to 50 to 60 mi/h, while a veteranprofessional soccer player can kick the soccer ball up to 80 mi/h.Vectors Gravity The vectors identified in the triangle describe theinitial velocity of the soccer ball as the combination of avertical and horizontal velocity. The constant g represents theacceleration of any object due to Earth’s gravitational pull. Thevalue of g near Earth’s surface is about ?32 ft/s2 . v x = v k cos? & v y = v k sin ?
1. Use the information above to calculate the horizontal andvertical velocities of a ball kicked at a 35° angle with an initialvelocity of 60 mi/h. Convert the velocities to ft/s. (2 pts)Project 2 368 MTHH 039 2. The equations x(t) = v x t and y(t) = v yt + 0.5 gt2 describe the x- and y- coordinate of a soccer ballfunction of time. Use the second to calculate the time the ballwill take to complete its parabolic path. (4 pts) 3. Use the firstequation given in Question 2 to calculate how far the ball willtravel horizontally from its original position. (2 pts)

1. Use the technique developed in Activity 1 tocalculate horizontal distance of the kick for angle in 15°increments from 15° to 90°? Make a spreadsheet for yourcalculations. Use the initial velocity of 60 mi/h. (8pts)
I want to know the answer of the last question that I write boldand italic. Let me know the answer of this questions!!!
