Question

Consider a projectile at the top of its trajectory. (a) What is its speed in terms of v° and θ°

Answer 1

Hello my friend

Here is your answer

So,

If the projectile at the top of its trajectory , then the speed in terms of v₀θ° is

v₀cosθ° Because if we resolve the velocity along x-axis and y-axis then velocity along x axis is v₀cosθ When a projectile at the top of its trajectory then its velocity along y axis is 0 but x axis will be v₀cosθ.

Hope it helps u the best
