The bacterium Escherichia coli (or E. coli) is a single-celled organism that lives in the gut of healthy humans and animals. When grown in a uniform medium rich in salts and amino acids, it swims along zig-zag paths at a constant speed changing direction at varying time intervals. Figure P1.62 shows the positions of an E. coli as it moves from point A to point J. Each segment of the motion can be identified by two letters, such as segment BC. During which segments, if any, does the bacterium have the same Figure P1.62 a. Displacement? b. Speed? c. Velocity?

An object's position in the as a function of time obeys the equation;
x(t) = 14.2/t2.17 + 5.1t3
where all constants have proper SI Units.
What is the speed of the object in the x direction at t = 1.93 seconds?
In an 8.00 kmkm race, one runner runs at a steady 11.2 km/hkm/h and another runs at 14.9 km/hkm/h.
How far from the finish line is the slower runner when the faster runner finishes the race?
Express your answer in kilometers to three significant figures.
A space shuttle’s coordinates as functions of time are given by x(t) = 7.0 t^3 and y(t) = 4.0t^2 - 2.1t , where x and y are in meters and t is in seconds. write a vector expression for the ball's acceleration as a function of time.
