A ball is kicked with a speed of 70ft/s at an angle of 45 degrees. Determine the total distance the ball travels, determine he height y when the ball reaches x=126 ft

Expert Solution

the total distance the ball travels = u² * sin(2theta)/g

= 70² * sin90/32.2

= 152.17 ft

Here, time , t = 126/(70 * cos45)

= 2.54 s

Thus, height y when the ball reaches x=126 ft = 70 * sin45 * 2.54 - 1/2 * 32.2 * 2.54²

= 21.85 ft
