Problem 1
The image below shows the successive positions of a person walking. The distance between two successive positions represents the length of a step, which is l = 60 cm.
a) Knowing that each step is taken in Δt = 0.8 s, draw a table of values in which to note the moment of time, as well as the coordinate of the person, for each of the eight positions represented in the image below.
b) Show the motion graph for the person walking.
Problem 2
Maria goes to school on a straight street. She uses an application on her mobile phone and records at different times the spatial coordinate she has with respect to her house. The data obtained are reproduced in the table below:
t (min) 0 1 2 3 4 5 6 7 8 9 10
Coord. x (m) 0 40 80 120 160 200 200 200 240 280 320
Show the motion graph and states the time interval during which Mary was at rest relative to her house!
