Odina walked down the hall at school from the cafeteria to
the band room, a distance of 100.0 m. a class of physics
students recorded and graphed her position every 2.0 s,
noting that she moved 2.6 m every 2.0 s. when was odina
in the following positions?
a. 25.0 m from the cafeteria
b. 25.0 m from the band room
c. create a graph showing odina’s motion.

Explanation:

As we know that when graph is plotted with the position and time then it shows that it will move with uniform speed

So here it is moving 2.6 m in 2 s

so speed is given as

Part a)

when she reach 25 m from cafeteria

time taken by her

Part b)

When she will reach 25 m from band room

then total distance moved from cafeteria is

time taken by her

Part c)

Since Odina is moving at constant speed

so the position time graph must be a straight line graph

it is a negative acceleration
