A golfer hits a golf ball at an angle of 30 degrees from the ground, with an initial velocity of 120 ft/sec. It lands on the ground, after 5 seconds

How far did the golf ball travel horizontally?

dа ta:

Vo = 120 ft / s

α = 30°

t = 5 s

x = ?

Formulas:

cos (α) = Vo, x / Vo = > Vo, x = Vo * cos (α)

x = Vo, x * t

Calculations:

Vo, x = 120 ft / s * cos (30) = 103.92 ft / s

x = 103.92 ft/s * 5 s = 519.6 ft

Answer: 519.6 ft
