**KINE 3301**Biomechanics of Human Movement Projectile Motion Chapter 5 Lecture 2**Two balls are released simultaneously from the same height.**At release both balls have an initial vertical velocity (Vyi) of 0 m/s. The green ball has a horizontal velocity (Vx) of 0 m/s, the blue ball has a horizontal velocity (Vx) of 10 m/s, which ball hits the ground first? If the green ball weighs twice as much as the blue ball which one hits the ground first?**A diver takes off with an initial height (yi) of 2.9 m and**an initial vertical velocity (Vyi) of 3.3 m/s, find the time (t) for the diver to go from takeoff, reach the peak and fall back down to the SAME HEIGHT as takeoff, a final height (yf) of 2.9 m.**A diver takes off with an initial vertical velocity (Vyi) of**6.2 m/s, find the time to the peak.**A discus falls from a peak height (yi) of 19 m to a final**height (yf) of 0 m, find the vertical velocity of the discus when it hits the ground.**A baseball is hit with an initial vertical velocity (Vyi) of**26 m/s and an initial height (yi) of 1.2 m, find the height of the ball (yf) after 4 seconds.**In the BeijingOlympics GuoJingjing diver had a vertical**velocity of −12 m/s when she was 1.8 m above the water. What was her peak height? [yi = 9.14]**A javelin is thrown with an initial height (yi) of 1.6 m,**initial vertical velocity (Vyi) of 15 m/s and a horizontal velocity (Vx) of 18 m/s. • Find peak height (yf) [yf= 13.07 m] • Find time to peak [t = 1.53 sec] • Find Vyf at landing, The final height (yf) is .7 m [Vyf = −15.58 m/s] • Find time down [t = 1.59 sec] • Find total time in air [t = 3.12 sec] • Find horizontal distance (x) [x = 56.12 m]**A hitter at Fenway hits a ball with an initial height (yi)**of 1.1 m, an initial vertical velocity (Vyi) of 27 m/s, and a horizontal velocity of (Vx) of 25 m/s. Did the ball go over the 11.28 m wall that is 94.49 m from home plate?**A hitter at Fenway hits a ball with an initial height (yi)**of 1.1 m, an initial velocity (Vy) of 32.33 m/s at an angle of 39.35 degrees. Did the ball go over the 11.28 m wall that is 94.49 m from home plate?
