106. 25 m

Explanation:

In this situation the following equations will be useful:

$V=V_{o}+at$ (1)

$V^{2}=V_{o}^{2}+2ad$ (2)

Where:

is the object’s final velocity

$V_{o}=25 m/s$ is the object’s initial velocity

$a=-1.5 m/s^{2}$ is the object's acceleration

t=5 s is the time

is the distance traveled

Finding from (1):

$V=25 m/s+(-1.5 m/s^{2})(5 s)$ (3)

V=17.5 m/s (4)

Substituting (4) in (2):

$(17.5 m/s)^{2}=(25 m/s)^{2}+2(-1.5 m/s^{2})d$ (5)

Finding :

d=106.25 m

answer:

''The tired of a car support the weight of a stationary. If one tire has a slow leak, the air pressure within the tire will '' with time, the surface area between the tire and the roadwill ' increase' in time and the net force the tire exerts on the roadwill 'remain constant' in time''.

''Answer is Decrease, increase, remain constant.''
