(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A speeder traveling at a constant speed of

109 km/h races past a billboard. A patrol car

pursues from rest with constant acceleration

of (8 km/h)/s until it reaches its maximum

speed of 141 km/h, which it maintains until it

catches up with the speeder.

How long does it take the patrol car to

catch the speeder if it starts moving just as

the speeder passes? Answer in units of s.

How far does each car travel? Answer in units

of km.

2. Relevant equations

Δx = vot + 1/2at^2

Δx = 1/2(vo + v)t

3. The attempt at a solution

This is an online assignment I am doing. I tried substituting values for the equations with the given info and tried to make it so the speeder equation and the car equation is the same so I can solve for the time and i got 27.3 but it came out wrong when I entered the question online. Since I cannot get the first part I can't get the second part either.
