Question

plz give the answer quickly with the solving​

Answer 1

Answer:

given t = 3 , v = 7 , s = 3

s = vt - 1/2 at²

3 = 7×3 - 1/2 a 3²

3 = 21 - 9a/2

3 = 42-9a/2

6 = 42-9a

-42+6 = -9a

-36 = -9a

a = -36/-9

a = 4

Answer 2

v =7
t =3
s =3

vt-1/2at square
(7×3)-1/2(a×3)square
(21)-1/2 (3a)square
21-1/2×9a square
20.5×9a square
Answer = 184.5a square
