Question

The following data describes the position of an object along the x -axis as a function of time. Plot the data and find the instantaneous velocity of the object, at a-5.0s, b-16s,c-23s

Answer 1

Gives

Graph value between position and time

Find velocity

$t=5sec\\t=16sec\\t=23sec$

$t=5sec$

$V_{t=5sec}=\frac{11.3-7.8}{5}=0.018m/sec$

$+x$ direction

$t=16sec\\V_{t=16sec}=\frac{20-20}{16}=0m/sec$

t=23sec

$$V_{t=23sec}=\frac{13.5-16.2}{23}=-0.013m/sec$$

$-x$ direction
