Question

9. The velocity of a particle increases from u to
vin a time t during which it covers a distance
s. If the particle has uniform acceleration,
which one of the following equations does
not apply to the motion?
A) 2s = (v+u)t
B) a =V-u/t
C) v = u2 - 2as
D) s = (u + 1/2at)t​

Answer 1

Answer:

C) v = u 2 - 2 as

Explanation:

because in the uniform acceleration the v²-u² = 2as

But dimensionally v² - u² = -2as is not correct

Answer 2

Answer:

B) a = v - u/t.

Explanation:

In above question 's' (distance) is metioned .

But in option B 's' is not mentioned .

Therefore option B does not apply to motion.
