TA: Tomoyuki Nakayama Tuesday, September 07, 2010 PHY 2048: Physics 1 with Calculus, Fall 2010 Review: Chapter 2.9-3.8 The purpose of this review is to refresh your memory. Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A. Free Fall A ball is shot vertically upward from the surface of another planet. A plot of y versus t for the ball is shown below, where y is the height of the ball above the starting point and t = 0 at the instant the bal is shot. The figure’s vertical scaling is set by y s = 60 m. Find the magnitude of the free fall acceleration of the planet and the initial velocity of the ball. B. Vectors In the figure a and b have magnitudes of 4 m and 3 m, respectively. The angles in the figure are θ 1 = 30º and θ 2 = 100º. Find the angle and magnitude of the sum of the two vectors.
