Before using any kinematic equations, resolve the initial velocity into its components using the launch angle Vertical component ( v0yv sub 0 y end-sub ): 2. Understand Key Principles
At the highest point of the trajectory, the vertical velocity is exactly zero ( ), while the horizontal velocity remains v0xv sub 0 x end-sub Projectile Motion - AP Physics 1: Unit 1 Review Supplement
), so the horizontal speed remains the same throughout the flight.
