physics help

on the sheet there are 20+ questions, basically we had to first use the air table which is raised at an angle, and pushing the puck upwards, and it will come down because of the gravity. Most of the questions are related to that, this question is just the last one and the most challenging one.

basically you are suppose to assume that the air table is raised at 25 degree angle, and you push the puck at the speed of 8m/s at 33 degree angle from the bottom of the air table. and find velocity of that puck half way up the air table. acceleration due to gravity is 9.8 m/s^2 down, but it's going to be reduced because it's at an angle.

edit: my friend showed me the answer on MSN, i still don't get what he did, but i'll just copy and paste that for the answer, the answer could be wrong but it's better than getting a 0 on this question.

here's he's answer:

vy= 8 sin(33)
vy=4.36m/s

vx=8 cos (33)
vx=6.71m/s

gi = -9.8 m/s2 * sin(25°) = -4.
Total vertical incline: dy-max = (02 – 4.362) / 2(-4.14) = 2.29 m
Velocity of the puck half way up the incline:
vy = sqrt[4.362 + 2(-4.14)( 2.29 / 2)] = 3.08 m/s
angle= tan-1(3.08 / 6.71) = 24.7 degrees
v = sqrt(6.712 + 3.082) = 7.38 m/s[24.7 degrees up the inclined plane]
