So : tan(30) = 8.3/Vy Vy = 8.3/tan(30) Vy= 14.4m/s V2y = 8.3 -9.8t 14.4 = 8.3 - 9.8t t= 0.622s y = 8.3t - 4.9t^2 y = 8.3(0.622) - 4.9(0.622)^2 y = 3.26m Therefore the haystack is 3.26m high??

You only have the angle, which is 30. How can you possibly calculate Vx and Vy??

well, as the skier gets of the ramp, V1x and V1y are both equal to 8.3m/s. 1) x = 8.3t 2) y = 8.3t + 4.9t^2 3) V2y = 8.3 + 9.8t Is this correct? If so, what are the next steps I should take?

the haystack is a post. The 30 degree angle is formed by the skier. what does x and y represent? and how am I supposed to find t?

Law of conservation of energy homework help! Homework Statement A skier goes down a slope and goes over a ramp. From a resting position which has a height of 16m, she leaves a ramp of 9m at an angle of 45 degrees and passes over a haystack forming a 30degree angle vertically. Supposing...
