hope this helps you..

Answer 2

Explanation:

Let;

d=distance

S=speed

t=time

s=displacement

v=velocity

So now;

S=dt

If we use velocity instead of speed…then the distance becomes displacement instead of distance hence;

v=st

s=v∗t

But obviously we will be using average velocity since velocity might not be constant throughout.

s=v+u2∗t

Now let's look at another equation;

a=v−ut, where a is acceleration, v is final velocity, u is until velocity and t is time taken

Rearranging this equation we get;

v=u+at

We substitute this value of v is the first equation we got;

s=u+at+u2∗t

s=2ut+at22

s=2ut2+at22

s=ut+12at2
