1. The problem statement, all variables and given/known data An automobile moves with constant speed down one hill and up another hill along a smoothly curved surface. In which direction will the velocity and acceleration of the car be when it is at its lowest point in its path? The car is pictured at the lowest point of a parabola. 2. Relevant equations 3. The attempt at a solution Being that this is Gen Physics 1, we are neglecting acceleration in the horizantal direction of motion so I choose the option which had the velocity vector as horizantal and in the direction of motion and I choose the acceleration which was straight down, due to gravity. I missed this question and the answers wont be up until Saturday, but I just can't wait to figure out where I went wrong in my analysis. Thanks in advance.
