The maximum height calculator is a tool for finding the maximum vertical position of a launched object in projectile motion. Answer (1 of 5): When the object is at its' maximum height, its' velocity will be 0. It is essential to understand that there are four basic forces operating on any object moving through the air. determined
At the highest point, the object has no kinetic energy where all of its kinetic energy is converted into the potential energy, and therefore the velocity is zero and the object does not accelerate. If somehow you knew the north-south and east-west position of the rocket at the top of its flight, then you'd only need one angle measurement. When will the rocket hit the ground?
