A projectile is launched with an initial velocity of 30 m/s at an angle of 30° above the horizontal. What is the horizontal component of the projectile's velocity?

A.B) 25.98 m/s
B.D) 60 m/s
C.C) 30 m/s
D.A) 15 m/s

Explanation

Core Concept

The horizontal component of velocity is given by vx = v₀cos(θ), where v₀ = 30 m/s and θ = 30°. vx = 30cos(30°) = 30(√3/2) ≈ 30(0.866) ≈ 25.98 m/s.

Correct Answer

AB) 25.98 m/s
