A Cork Shoots out of a Bottle at 36 degrees
The Cork Travels a Horizontal Distance of 1.5 Meters in 1.2 Seconds.
What is the Initial Speed of the Cork
(I've tried 1.25, 0.9 and 3.93)
Answer is NOT 1.25, 0.9, or 3.93 .. Tried and turned out incorrect)
1.72 Is Incorrect. :(
SOLVED: Correct Answer is 1.55

The initial velocity of the cork can be resolved into two components: one vertical and the other horizontal. The horizontal component is V x cos(theta); Where: V, is the velocity you are trying to find and theta is the angle of 36 deg.
In general, the distance travelled equals Velocity x time
Sx = Vcos(36) x t
V=Sx/cos(36) x t
V = 1.5/cos(36) x 1.2
V = 1.5/0.971
V = 1.54 m/s
