Question

V²=u²+2ass
U=12 a=-6 s=9

Work out a value of V.
Your final line should say , V=
Please help!!!!

Answer 1

Answer:

Step-by-step explanation:

V=u2+2as

V=12*12+2*(-6)*9

V=144+(-108)

V=144-108

V=36m/sec

Answer 2

$\sf{\large{\underline{\underline{EXPLANATION:}}}}$

★Given,,

• u=12

• a=-6

• s=9

★Therefore,,

$\mathtt{\boxed{v^{2}-u^{2}=2as}}$

$\sf{\implies{v^{2}-12^{2}=2(-6)(9)}}$

$\sf{\implies{v^{2}-144=-108}}$

$\sf{\implies{v^{2}=-108+144}}$

$\sf{\implies{v=\sqrt{36}}}$

Therefore,,

$\sf{\implies{v=6}}$

$\rule{200}2$
