Consider the position function s(t) = sin (at) representing the position of an object moving along a line on the end of a spring. Sketch a graph of s together with the secant line passing through (0,s(0)) and (0.8,s(0.8)). Determine the slope of the secant line and explain its relationship to the moving object. Sketch the graph of s together with the secant line. Choose the correct graph below. O A. O B. O C. OD. 1.5- 1.5 1.5- ent onT ent Determine the slope of the secant line. msec =(Round to the nearest thousandth as needed.) What is the relationship of the slope to the velocity of the moving object? A. The slope is the average velocity of the object over the interval [0,0.588]. O B. The slope is the average velocity of the object over the interval [0,0.8]. O C. The slope is the instantaneous velocity when t = 0.8. O D. The slope is the maximum velocity of the object
