Playing shortstop, you pick up a ground ball and throw it to second base. The ball is thrown horizontally, with a speed of 22 m/s, directly toward point A (Figure 413). When the ball reaches the second baseman 0.45 s later, it is caught at point B. (a) How far were you from the second baseman? (b) Wh

Consider a damped oscillator with p < No. There is a little difficulty defining the "period" r1 since the motion (5.38) is not periodic. However, a definition that makes sense is that r1 is the time between successive maxima of x (t). (a) Make a sketch of x (t) against t and indicate this definition

Five percent excess air is used in burning the reformer fuel; it is drawn into the system at 30C and 70% relative humidity. Estimate the average molecular weight of the air. Why does it differ from the value of 29 determined in Example 3.3-4 even though the ratio of nitrogen to oxygen is the same? De
