Hi, I'm new on this forum and don't really know how to use it, but I really need help I need to figure our 2 different experiment methods to answer these questions: -if an object is launched vertically, what was the initial velocity? -if an object is launched horizontally, what was the initial velocity? -what is the speed of a vehicle moving in constant motion? (already thought of the kinematics method, so I only need 1 other method) -if an object is attached on a string and is being spun in a vertical circle, what is the minimum speed to keep it moving in a circle? -if an object is on a turntable, what is the max speed without it slipping off? I need to make 2 experiments (different methods) each in order to answer these questions. Please help! Thanks!
