Answer 1

use v=u+at
and s=ut+(at^2)/2

Answer 2

what is 1.5m/s*s here ? Is it u (Initial velocity) or a (acceleration)

Answer 3

i got the v=u +at part

Answer 4

acceleration

Answer 5

ok....tysm

Answer 6

wait a sec, then u becomes - 1.5 m/s

Answer 7

can it be negative?

Answer 8

how can it be negative? its not coming negative check the calculations please!
