Question

For the $6^{th}$ to $8^{th}$ second, what was the student's movement?

$Distance/m$	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$6$	$6$	$3$	$0$
$Time/s$	$0$	$1$	$2$	$3$	$4$	$5$	$6$	$7$	$8$	$9$	$10$

Answer 1

formula,

speed = distance / time

$V=\frac{s}{t}$

$V$ at $t=6sec$

at $t=6sec\to s=6m$ (given)

$\therefore V=\frac{6}{6}=1m/s$

$V$ at $t=8sec$

at $t=8sec\to s=6m$ (given)

$\therefore V=\frac{6}{8}=0.75m/s$
