Question

can any1 help me in physics please

Answer 1

prove
\[s=ut+\frac{1}{2}at^2\]

Answer 2

i think i can wait.....

Answer 3

\[average velocity=(v+u) \div2\]
\[distance covered,s=average velo timestime\]
=\[[(v+u)\div2]timest\]
=\[[(u+at+u)\div2]timest\]
=\[(2ut+at ^{2})\div2\]
=\[ut+(1\div2)at ^{2}\]
therefore s=\[ut+(1\div2)at ^{2}\]
hope this helps
sorry that i made u wait:)

Answer 4

times means 'x'

Answer 5

its ok
