hi experts, KarishmaB Bunuel chetan2u
saw this DS question in one of mocks earlier, but i dont have access to it rn, so penning it out of my memory.
If the equation d=-4t^2+at+b represents the distance travelled d during time "t". and a and b are constants. what is the value of a?
1. at time t=2, the distance travelled was 40
2. the object was at height 20 initially
A. stat 1 suff
B. stat 2 suff
C both together
D alone suff
E none

Will need to see the actual question. By distance travelled, you mean height of the object? Is the object thrown from a height? That is what it looks like.
In that case, statement 2 will give us 20 = 0 + 0 + b so b = 20
and statement 1 will give us 40 = -16 + 2a + b
So using both you can get a.
