Hello! I have started to take a correspondence grade 12 physics course from www.ilc.org (affiliated with Toronto District School Board). After my first two weeks of working through the course I have covered Kinematics as well as Motion in Two Dimensions- Projectile Motion. My findings so far have been that practice materials in the textbook provided have been very light. The way that this course is graded is through a series of 'key questions.' Unfortunately, as I am solving these key questions (especially the ones that are math related) I am not very confident in my ability to get them right. I think that if I was able to solve more practice questions I would become more confident when solving the key questions, as well as gain a more lasting knowledge of the materials covered. So in this light I would like to find a book that has lots of practice questions and full solutions (very important) for the material covered in this course. I was hoping that I could get some advice on that matter from this forum. Topics covered in the course include: Kinematics Motion in Two Dimensions- Projectile Motion Dynamics: Newtons Laws- Force and Motion Circular Motion Energy and its Forms Simple Harmonic Motion Momentum in One and Two Dimensions Gravitation and Gravitational Fields Electrostatics Electric Fields, Potential, and Current Magnetism Applications of Electromagnetism Properties of Waves The Nature of Light The Electromagnetic Spectrum Applications of the properties of Light Special Theory of Relativity Early Quantum Mechanics Nuclear Reactions and their applications Elementary Particles To give an example of the difficulty level of material covered in the unit that I am working on now, i will post the set of 'key questions' that I will be graded on. 1. A bird takes 8.5s to fly from position A to position B along the path shown in figure 2.17. (Figure 2.17 shows a curve with the instantaneous velocity of the bird at point A and point B) Determine the bird's average acceleration. 2. A child throws a snowball with a horizontal velocity of 18 m/s directly towards a tree, from a distance of 9.0m and a height above the ground of 1.5m. a) after what interval does the snowball hit the tree? b)At what height above the ground will the snowball hit the tree? c)Determine the snowball's velocity as it strikes the tree. 3. In it's final trip upstream to its spawning territory a salmon jumps to the top of a waterfall at 1.9m high. What is the minimum vertical velocity needed by the salmon to reach the top of the waterfall? 4. A swimmer set out from the shores of New York and maintained a velocity of 4 m/s [N]. As the swimmer approached the ontario shore, she encountered a cross-current of 2 m/s (E25S). Calculate her velocity with respect to the crowd observing from the beach. Thanks!
