Ответ:
The horizontal component of the velocity is approximately 42.6 m/s
Explanation:
The given parameters are;
The speed of the arrow when it was shot = 52 m/s
The angular direction in which the arrow was shot, θ = 35° above the horizontal
The horizontal component of the velocity is found by the resolution if the velocity vector into its components as follows;
The horizontal component of the velocity = Velocity in the x-direction = vₓ
vₓ = v × cos(θ) = 52 × cos (35°) ≈ 42.6 m/s
vₓ = The horizontal component of the velocity ≈ 42.6 m/s
