Answer 1

Answer:

i dont no answersorry hhijl

Answer 2

$\huge\bold{Añswer}$

We know that,

The distance travelled in 'n' second is

• Sn = un + ½ an²

And Distance travelled in 'n + 1' seconds is

• Sn + 1 = un + ½ a(n + 1)²

So, the distance travelled in 'n' second is

• Sn - Sn + 1

Which comes out to be

• u + a(2n + 1)/2

where,

• Initial speed = u
• nth second = n
• acceleration = a
