Below is a graph of y=f^(')(x). Given f(0)=0, draw a graph of y=f(x). Use the given areas of triangles and rectangles to help you plot known y-values on your graph of y=f(x). (16pts)
pIOt a poInt ror every IIVIEGEK value or x.
A driver applies the brakes to her car and slows to a stop with constant deceleration. If she was traveling 60mph when she applied the brakes and it took her 20 seconds to stop, how far did she travel? Think about what v(0) is and v(20) is. Pay attention to units! Try converting miles per hour to feet per second. Show how you came up with your conversions. (10 pts)
A subway train travels 2440ft. between two stations. It starts from rest and accelerates at a rate of 4(ft)/(sec^(2)) until its velocity reaches a cruising speed of 40f(t)/(sec). It then moves at this constant velocity for a while before slowing to rest at the next stop with an acceleration of -5(ft)/(sec^(2)). Find the total time for the trip between the stations. (10 pts)
3.Below is a graph of y=fx.Given fO)=O,draw a graph of y=fx.Use the given areas of triangles and rectangles to help you plot known y-values on your graph of y = f(). (16pts)
y=f'(x)
Note,your graph is a series of piecewise parabolas and 2 non-horizontal line segments plot a point for every INTEGER value of x.
