Unformatted text preview: 1 Chap 8 Potential energy and conservation of energy Note – this is an outline of the lecture, print this and take notes on it in lecture It is not the and take notes on it in lecture. It is not the complete lecture. You should attend lecture to get the complete notes Images taken from Halliday/Resnick/Walker, Fundamentals of Physics, 7 th Edition, John Wiley and Sons Inc., by permission. Hints P22 a) Argue that the maximum tension must be at the lowest point of the swing. Do a free-body diagram for this point. Note that Tarzan is undergoing circular motion at this point. P25 . Find the skiers launch velocity using conservation of mechanical energy. Then use this to find the maximum height to which he rises. P.48. b) you need to find using P49. Its easiest to start with work-KE theorem P68b) you can find the work done on the bullet while it is penetrating the wall, and therefore find the average F. th E U K Δ − = Δ + Δ Work and Potential Energy-Gravity W U − = Δ Work and Potential Energy-spring force W U − = Δ SP8-1 A 2.0 kg block of slippery cheese slides along a friction- less track from point a to point b . The cheese travels through a total distance of 2.0 m along the track, and a net vertical distance of 0.80 m. How much work is done on vertical distance of 0....
