Answer 1

use one of the kinematics equation with x in it. Then solve for x

Answer 2

you can use x = Vi * t + 1/2 at^2

Answer 3

you have everything, so just plug stuffs in to find x,

Answer 4

use the kinematics equation

v^2 - u^2 = 2as
where v is final velocity which is zero
u is initial velocity when it start slowing down which is 30m/sec
a is the acceleration ,which is - 0.065 m/sec^2
s is the distance moved while slowing down

putting these values in the equation you will get the value of s
which is 6.9 km
