Question

pls give the solution of both the que

Answer 1

1- the body is moving with uniform acc 'a' and the time interval is Δt...
so the formula of acc is a=change in velocity(v)
-------------------------
time interval(Δt).
so change in velocity(v) becomes =a*Δt
and hence option 3.

Answer 2

1) We Know the Mathematical formula of acc.

Δv/Δt = a

So Δv = aΔt

So Option (C) is correct

2) We Know the formula

S = $u + \frac{a}{2} (2t - 1)$

So putting values

u = Vo

a = a

t = nth

We Get

S = Vo + a/2 (2n-1)

So option (D) is correct
