Unformatted text preview: May 16, 2008 PHY2053 Discussion Warm Up Quiz (Appendix A) Name: UFID: *1. Determining an angle is essential to solve problems in physics 1. Suppose a person is towing up a block on a 15 incline by pulling a string attached to the block. The string makes 20 to the incline. Find the following angles (0 90): (1). The angle the string makes to the vertical. (2). The angle the string makes to the line perpendicular to the incline. The string makes an angle of 35 (= 15+20) to the horizontal. Thus, the angle the string makes to the vertical is 9035 = 55. Since the string makes 20 to the surface of the incline, thus the angle between the string and the line perpendicular to the surface is 9070 = 20 ***2. When you throw a ball, the height of the ball is given by a quadratic function of ***2....
