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 θ 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 90˚-35˚ = 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 90˚-70˚ = 20˚ ***2. When you throw a ball, the height of the ball is given by a quadratic function of ***2....
