TA: Tomoyuki Nakayama Monday, September 13, 2010 PHY 2048: Physics 1 with Calculus, Fall 2010 Review: Chapter 4.1-4.7 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. Projectile Motion At what initial speed must the basketball player in the figure throw the ball, at angle θ 0 = 50º above the horizontal, to make the foul shot? The horizontal distance from the release point to the basket is d = 4.0 m, the height of the release point is h 1 = 1.8 m and that of the basket is h 2 = 3.0 m. B. Uniform Circular Motion A particle moves in uniform circular motion over a horizontal xy plane. At one instant, it moves through the point at coordinates (4.00 m, 2.00 m) with a velocity of -4.00 i + 3.00 j m/s and an acceleration of –12.0 i m/s 2 – 16.0 j m/s 2 . Locate the center of the circular path.
