At a given angle, I don't know. At the 4 angles in task 1 I thought I was onto something (WF=Fs=Δmv2/2). However, I just realized that, i.e., F does not add 10m*10 kinetic energy units from P0 to (5, 0), as F does work on both the speed and C all the way. Working on general velocity now...

So, this seemed really fun to me until I got stuck. THE TASK is about an object with mass m, moving in a basic (2D) coordinate system. It is attached to origo (0, 0) by a "rope" with constant length r=5. In position P0(-5, 0) it has the velocity v0=[0, -10]. Hence, the object moves around origo...

Hi, I am a senior year high-school student (as of 2015-2016) and am taking physics and mathematics. What I like the most is the combination: solving physics problems mathematically. My intention on physicsforums.com is to ask about problems that I am curious about, and follow other interesting...
