I need help with the exercises attached in the pictures. Basically, exercise 3 is already solved but I need some help understanding every subpoint (for example, at a) how did we get to 0=H -g* tAO/2 , I know it's from the motion law and vA=0, but why is y(t)=0?). And I tried solving ex 8, but I need help at a) and c). I calculated the velocity and the acc but I don't know how I could find the angle between the two (cross product was my guess but I'm not sure), and c) I know that to find the trajectory eq I need to eliminate time, but I don't know for sure how I'm supposed to do that. Even if you don't explain both exercises or not all subpoints, anything is appreciated as I have a test next week and I need to understand. Thank you!
