I'm trying to relearn physics the summer. I've been studying some basic calculus and I've enjoyed it. But I'm going back to solving problems that don't involve any calculus, such as kinematics (like using the suvat equations). Now the problem is I'm having a very difficult time solving some questions,specifically a stone being thrown vertically upward off the edge of a cliff, then I have to find its speed before it hits the ground, time in air, total distance. One such problem took me about 30 mins to do. When you guys were learning physics were you guys troubled with this kind of introductory stuff?
