Question

1. using the distance vs. time graph below, write a story that describes the movement of an object.

d (m)
60
40
20
0
0 10 20 30 40 50 60 70
t (s)
a
b
c
d
e
f

Explanation:

The object starts at rest (segment a). Then it speeds up (segment b). After that, it moves at a constant speed (segment c). Next, it slows down and stops (segment d - e). Finally, it moves back towards the starting - point (segment f).

Answer:

A person is standing still for the first 10 seconds (segment a). Then they start running faster and faster for the next 10 seconds (segment b). After that, they run at a steady pace for about 20 seconds (segment c). Then they gradually slow down and stop for 10 seconds (segment d - e). Finally, they turn around and walk back towards their starting position for the last 10 seconds (segment f).
