Alex goes cruising on his dirt bike. He rides 700 m north, 300 m east, 400 m north, 600 m west, 1200 m south 300 m east and finally 100 m north. What distance did he cover? What was his displacement?
The motion of a person as seen by another person is described by the equation v=-3.0m/s+0.5m/s^2t.
Draw a motion diagram.
draw a motion potion vs time graph
draw a motion velocity versus time graph
draw a acceleration vs time graph
say everything you can about this motion and what happens to the person when his speed becomes zero.
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, these bacteria swim along zig-zag paths at a constant speed of 20 μm/s. Figure shows the trajectory of an E. coli as it moves from point A to point E. Each segment of the motion can be identified by two letters, such as segment BC.
a. For each of the four segments in the bacterium’s trajectory, calculate the x- and y-components of its displacement and of its velocity.b. Calculate both the total distance traveled and the magnitude of the net displacement for the entire motion.c. What are the magnitude and the direction of the bacterium’s average velocity for the entire trip?
