The projectile is launched onto a hill, which is defined by the function. An object is launched at a velocity of 20 ms in a direction making an angle of 25 upward with the horizontal. Once the object has been thrown, the only acceleration is in the y vertical or updown direction. In projectile motion, the initial horizontal velocity is the final horizontal velocity. Using horizontal and vertical axes through o allows the position of the projectile at any point in its motion to be given in terms of two coordinates x, y.
Projectiles always maintain a constant horizontal velocity vx. A projectile is launched with an initial horizontal velocity from an elevated position and follows a parabolic path to the ground. For a projectile, the rising and falling times of the object are equal if the launching position is the landing position. The initial velocity for each firing was likely to be the same.
