Question

With the usual notations the following equation S_(t)=u+1/2a(2t-1) is

Answer 1

Answer:

......

.

option c......

Answer 2

Answer:

Well,firstly I must praise you for your observation,you have nicely detected a problem.

Well,looking into how the eqution was derived,you will get that,

It tells us about displacement in unit second,as we calculate by subtracting displacement occured in

(

t

+

1

)

th

s

- displacement occured in

t

th

s

So,apparently,the displacement we calculate from the equation is displacement occured in

1

s

which corresponds to velocity,

So,basically

S

t

is

S

t

1

s

so it has the dimension of

[

L

T

−
