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 = Vxi2. (delta)x = Vxi * (delta)t3. Vyf = 9.8 m/s^2 * (delta)t4. (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."

You will have four equations total, two for the horizontal and twofor the vertical direction.To perform this experiment, we will roll an object down a ramp and launch it horizontally as shown inFigure 4.2. The object then will be in free-fall. We will measure the distance it falls (Ay) and the distanceit travels horizontally (Ar). The object's initial velocity is then calculated using the kinematic equation.(0 = 7)Ay(1)p--X-Figure 4.2: Schematic drawing of the experiment.PROCEDUREWhile following the procedure, refer to Figure 4.3 for the setup of the ramp.
