I need help with Q4. I can't figure out what equation I should use to find the velocity. I think it would be a combination of the velocity formulas for x and y but I'm not sure. My 4 simplified equations are: 1. Vxf = Vxi 2. (delta)x = Vxi * (delta)t 3. Vyf = 9.8 m/s^2 * (delta)t 4. (delta)y = 1/2(9.8 m/s^2) * (delta)t^2 For my data I have: (delta)y = 0.6604 meters (delta) t = 0.367 seconds I don't need the answer or a long explanation, I really just can't figure out what equation/formula I need to use to find "the velocity of your object as it rolls off the incline and enters free-fall."
