TBR Physics Section I Passage IV Question 25....
Why would you use the formula, Vy^2 = Voy^2 +2adeltaY, to compare deltaY and Voy^2??
Why not use another formula relating velocity and deltaY.... such as Y = Yo + VoyT +1/2AT^2??? And say that velocity and deltaY are linearly related??
I have to be missing something here?!
Also, can provide a simple explanation that explains the difference between simple projectile motion (passage I) and this slingshot example (passage IV)? Im not getting this!
Thanks in advance!
