I'm having trouble with these two problems. We haven't covered this in class yet, but I have to do them for my lab tomorrow. 1. A package is dropped from a passing plane(moving in the horizontal direction) and produces a projectile motion as it is falling to the ground. If it takes the package only 50 seconds until it hits the ground, how far above the ground was the plane when the package was released? in meters. How do i know what equation to use for this? 2. A ball rolls horizontally off the edge of a tabletop that is 1.5m high. It strikes the floor 2.80m away from the edge of the table. What is the initia (horizontal) velocity of the ball? in m/s. I don't know what equation to use for this either. There are so many in the text, but we haven't gone over problems like this yet. Please help!!
