use your commonsense
just use the first equation of motion
v=u+at
so by substitute the of v=0, u=200, a=20, t=?
v=u+at
0=200+20t
-200=20t
-10=t
since in classical mechanics time can not be negative so in 10seconds its velocity will be doubled and as velocity is doubled then acceleration must also be doubled
2》this question I have done
so just I will tell you the formula
v=u+at (where a=g)
(and please cut your nails) ("_*)
