The formula for velocity vf = vi + at
First list your given information
2m/s Is your initial velocity (vi)
6m/s is you final velocity (vf)
2 seconds is your time (t)
Since you want the a for acceleration get a by itself
a = (vf-vi)/t
So a= (6-2)/2
a= 4/2
a=2
Now units
the units for acceleration are m/s
2m/s

Answer:
Explanation:
Height of the cliff is given as
now the time taken by the diver to hit the surface is given as
Now in the same time it has to cover a distance of 13.39 m
so the speed in horizontal direction is given as
As per Newton's II law we know that
rate of change in momentum is Net outside force on the object
now here we will have if net outside force will be zero
then we can say
so from above equation we can say
and hence we have
so the correct answer will be
<em>3.) in the absence of outside forces</em>
