A projectile has an initial horizontal velocity of 24 m/s. What is the horizontal velocity at the max height? Explain all work.

Explanation: Let the initial velocity be x₀

According to the question, x₀cosθ = 5m/s

And x₀sinθ = 6.5m/s

Angle of projection = ?

Let the angle of projection be θ

So,

x₀sinθ / x₀cosθ =

We know,

sinθ / cosθ = tanθ

Thus,

tanθ =

tanθ = 1.3

θ = tan⁻¹ (1.3)

θ = 52.4⁰
