A famous golfer strikes a golf ball on the ground, giving it an initial velocity v = v0xi + v0yj. Assume the ball moves without air resistance and its motion is described using a Cartesian coordinate system with its origin located at the ballʼs initial position.
v0x = 6 m/s
v0y = 3.4 m/s

Em = Ep + Ec = m.g.z + m.V²/2 = cste
g.z○ + V○x²/2 + V○z²/2 = g.z○ + g.h + V○x²/2 + 0
h = V○z²/(2.g) = 3,4^2/2/9,81 = 0,589194699 = 0,59 m

Az = d²z/dt² = - g
Vz = dz/dt = V○z - g.t
Dz = z-z○ = V○z.t - g.t²/2
▬
Vz(T) = 0
T = V○z/g
Dz(T) = h = V○z²/(2.g) = 0,59 m

use vf = vi + at and remedy for vi whilst t = 4.5 and a = -32 and vf = 0 using fact its at its maximum then use that vi (that's a hundred and forty four ft/s) interior the equation d = vit + a million/2at^2 t = 5.7 (4.5+a million.2) very final answer could be 3 hundred.ninety six ft
