a= 0
because const speed

FIRSTLY AS V=CONST THEN a = 0;
NOW FOR's WE KNOW THAT AREA UNDER v&T gives distance change.
So that (10*80)/2 + 30*80 = 2.8km.
NOW FOR's WE KNOW THAT AREA UNDER v&T gives distance change.
So that (10*80)/2 + 30*80 = 2.8km.

But the velocity has increased to an extent and so acceleration should have increased before becoming constant. Shouldn't that still be the acceleration at 40s.
