34.(2)..
$\textbf{Explanation}$-
Let the v at angle of 30° be a
then v at angle of 90-30 = 60° = 4a [since, the object is hitting double distance in half time...
=> v = s/t
now, v = 2s÷t/2= 4s/t
thus ratio = 1/4

35. (2)
$\textbf{Explanation}$-

we know that the s distance covered = area of the ∆

=> base = 10s
height = 12 m/s
area = 1/2×10s × 12m/s = 60 m

also u can find it by using acceleration formula.☺️

36.(2)
$\textbf{Explanation}$-

we know, that s = ut+at²/2
here since u =0 therefore
s = 9.8×16/2
s = 78.4m

37.(c)
$\textbf{Explanation}$-

zero acceleration = uniform/constant velocity
which can be seen in graph 3

38.(1)
$\textbf{Explanation}$-

we know that average speed = distance/time
remember the difference btwn
$\textbf{Distance}$ and $\textbf{Displacement}$

☺️☺️☺️☺️☺️

$\textbf{Remember}$
for NTSE it must be ur timing and perfection.
also, u must learn to make answers with options as it takes lesser time.
U may face some questions with similar answers where u can get confused ....in those cases ...solve it!...

☺️☺️☺️
