If a projectile is projected with kinetic energy.having maximum possible horizontal range.then what will be it's kinetic energy at highest point?
kinetic energy at highest point is
At highest point of any projectile, the vertical component of its velocity has decayed to zero. Therefore, its only velocity at that point is its horizontal component (and the kinetic energy will be at the minimum value of its flight). To be projected for highest range, the elevation,
Let the initial velocity be
Therefore its kinetic energy at the highest point will be
I hope this helps,
