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."
a. Find the velocity v(t) and acceleration a(t).
b. At what value of t does v=0?
c. What is the maximum height?
Given is the data for speed of blood in the aorta. Determine the magnitude of the acceleration for both phases, speeding up and slowing down.
