Projectile Motion: Calculating Initial Speed for Arrow at 30° Angle

[QUOTE="Epic Mango, post: 4945959, member: 535515"] Sorry, but 20 is not the answer. In fact, there is a much easier way to do this problem, using one formula. The formula is: R = v[SUB]i[/SUB][SUP]2[/SUP]*sin(2θ)/g R is the range, or your horizontal distance. If you check with this, it gives you the value of v[SUB]i[/SUB] as ~33.6 m/s. Generally, however, the "long" way of doing the problem is better. This is just a really quick shortcut, but you won't actually learn anything the short way. :D [/QUOTE]
