Question

Complete the following table assuming constant acceleration:

u (m/s)	a (m/$s^2$)	s (m)	$v(v^2=u^2+2as)\left(m/s\right)$
3	5	- - -	7
- - -	2	11	12

Answer 1

For row $1$

$v^2=u^2+2as$

$7^2=3^2+2\times 5\times s$

$49-9=10s$

$s=4m$

For row $2$

${12}^2=u^2+2\times 2\times 11$

$144-44=u^2$

$u^2=100$

$u=10m/s$
