Good evening. I'd like to first start by saying I am new to this forum, and I am a physics noob. I know that very fact will help people shy away from trying to help me answer this question. This problem (which an image is posted) is 1 of 5 questions on a take home kinematic quiz. I've managed to answer all of them (correctly, I hope) except for this one. One of the issues, I am having with this question is that I've never seen a similar problem. Also, some of the language in the problem may be confusing me. 1. The problem statement, all variables and given/known data A car is traveling the circle shown between points A + B at a constant speed of 10 m/s. The radius of the circle is 100m. There is a theta sub a (30 degrees) and a theta sub b (60 degrees). I wrote everything that I could, but I've attached an image that shows everything. a) Find the components of V_a and V_b b) Compute delta V (keep in component form) c) If it takes 10s to go between points A and B, what is the acceleration, in component form and magnitude angle form? Relevant equations a= delta v/delta t components of vectors 3. The attempt at a solution First off, the problems states the car is traveling at a constant speed, so doesn't that mean acceleration = 0? But part c wants me to find the acceleration...? If its going at a constant speed, how is there a change in velocity for part b? These two things are confusing the crap out of me. So far, I've started to find the components of V_a (hopefully the right way) V_ax = (cos30)(10) V_ay = (sin30)(10) If this is the correct way to figure out the components, then I think I can get parts A and B of this question. Any guidance would be greatly appreciated.
