1. The problem statement, all variables and given/known data A competitive mini-golf player notices an opponent's ball situated 50cm in front of a wall containing two tunnels. One tunnel leads to the hole, the other to a bunker. The player skillfully putts their ball due East at the opponent's ball with a velocity of 4m/s. The opponent's ball is knocked 20 degrees to the South of East with a velocity of 1.7m/s into the tunnel leading to the bunker. Meaning the player's ball travels into the second tunnel located North of East (to great applause from spectators). If the player's ball weighed 40g, and the opponent's ball weighed 45g, how far apart were the centres of the two tunnels? 2. Relevant equations Velocity = displacement/time Force = G*(mass1*mass2)/(distance^2) 3. The attempt at a solution Using the above formula, transpose so distance can be found. (distance^2)=G*(mass1*mass2)/force I'm not sure where to get the value for force though if this is the correct method. I have tried drawing a diagram myself but am stuck and don't know what to do. I hope someone can help me with this problem, work through it with me or point me in the right direction. Any help would be appreciated!
