[QUOTE="dejavu333, post: 6650798, member: 702716"] [B]Homework Statement:[/B] velocity:20m/s we're on 5m, target is on 10m. What are the possible launching angles? The diatance is 40m Air resistance can be neglected. [B]Relevant Equations:[/B] none if the target is lower than me, the formula is below, but if it's higher as in the task, a whole different formula is required I think. a = 9.8 * distance^2 / velocity^2 phi = Arctan(distance / height_diff) angle_if_elevation = ( Arccos((a - height_diff) / Sqroot(height_diff^2) + distance^2)) + phi ) / 2 [/QUOTE]
