1. The problem statement, all variables and given/known data A skier travels with a constant speed of 6 m/s along a parabolic path y= x2/20. Find the acceleration of the skier when he is at (10,5). Neglect the size of skier. 2. Relevant equations dy/dx is slope of parabola. In a straight line if body has distance covered=x, then velocity (v) = dx/dt and acceleration = dv/dt Radial acceleration is v2/R where R is radius. 3. The attempt at a solution Slope is 2x/20= x/10. For straight line determining acceleration is easy but how about this curve case?
