# Calculator: Throw Distance at Angle

Calculate the distance of an object thrown at a certain angle, without air resistance. The air resistance is neglectable at compact, heavy objects and a velocity reached at normal throwing, it only slightly decreases the distance. So the distance depends on launch speed and the trajectory angle. A 45 degrees angle is ideal if, as assumed here, launch and landing point have the same height. The trajectory is an upside down parabola. The formula for the distance is

Launch velocity or thrown distance can be calculated from the other three values.

Example: a stone, thrown with 70 kilometers per hour, can fly up to 38.5 meters. But thrown at a 30 degrees angle, it flies only 33 meters.
