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

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

a and b sometimes have a positive value
