Answer 1

Dn = u + a/2 {2n-1}

Answer 2

u knw this formula

Answer 3

no

Answer 4

it is the formula to find distance travelled in nth second

Answer 5

okay .. teach me :)
what is Dn ?

Answer 6

Dn is the dist travelled in nth second.. u is the initai speed.. a is the acceleration and n is the nth second.. :)

Answer 7

okay .. tnx @pavaneinstine :)
