Problem 1, 1D motion and vectors: An object is released from rest at a height h. During the final second of its fall, it traverses a distance of 38 m. Determine h. Choose a coordinate system with the origin at the point of release and downward as the positive direction. Ignoring air resistance, the acceleration of the object is constant a=g=9.81 m/s. Draw a picture of set-up showing the y-axis direction What are the given kinematic variables, and the variable you want to solve for? Write the relevant equations (no numbers) that you will use to find the needed unknowns. Identify the unknown values. Solve the system of equations algebraically, so you have an expression, in terms of your labeled variables, for each of the quantities you want to know. Do not pug in any numbers yet. Add numbers and units, solve for final value(s). Evaluate: Show that your units work out. Are your values reasonable? Does the angle look right? Do these times match your expectations?
