, t {xi , xf ,vix ,vfx , ax. Yi,yf ,viy ,vfy , ay } - checklist. * find the stated known values as well as the implied values. (ex. at max height, vfy = 0) * figure out which one(s) they want you to solve for. X = v0 t + a t2. Two types of projectile motion problems: (1) all info is given from the problem statement. (2) all info must be found on a graph. * if you go up you take the derivative slope of the line. * if you go down you take the integral area under the curve. * is finding the slope between two points on a graph. (ex: vavg is found from the x- graph) * taking the derivative and plugging in for the desired time or. * integrating and solving for the constant (initial conditions must be given to do so)
