Chieffy caligdong of the philippine azkals kicked a football with an initial velocity of 20. 0 m/s at an angle of 60. 0a. How long did the ball stay in the air?b. What are the range and maximum height of the ball?.

a. Time

t = 2 vo sin (α)/ g

t = 2 ( 20.0 m/s) sin (60°) / 9.8 ms-²

t = 34.64 m/s / 9.8 ms -²

t = 3.53 s

b. Range and maximum height

Range or dx = vo²/ g sin 2(α)

dx = 20.0m/s² /(9.8) sin 2 (60°)

dx = 35.347 m ≈ 35.35 m

Maximum height or h = V₀² * sin(α)² / (2 * g)

h = (20.0)²sin (60°)² / (2)(9.8 m/s)

h = 15.290 m ≈ 15. 29 m
