Question

The graph describes a bicycle racer's distance from a roadside television camera s(t) 1400 120 100 (130,1097) a) When is the bicyclist's velocity the greatest? How can you tell? b) Is the bicyclist's acceleration positive or negative? How can you tell? 800 600 200 10,227 0 0 20 40 60 80 100 120 140 160 Time (in seconds) a) The velocity is greatest at timebecause the slope of the tangent line is | there b) The acceleration is Vbecause the slopes of the tangent lines stay the same are decreasing are increasing re nter vour answer in the answer box 2

Explanation / Answer

a. Velocity is greatest at x=0, because slope of tangent is maximum there.

b. The acceleration is negative because slope of tangent lines are decreasing.
