Question 546790
A stationary police car spots a vehicle traveling at speed. 
The police car accelerates flat out to apprehend suspect.
How fast in km/h would the police car have to travel to catch up to and match speeding cars speed within 3.3 kilometers if the speeding car is traveling at 144km/h?
:
Let s = speed required by the cop to catch the unfortunate driver
:
The average speed of an car accelerating from 0 = half the final speed
:
Find the time it takes the speeding car to cover 3.3 km
{{{3.3/144}}} = .0229 hrs
:
therefore a distance equation, d = speed * time
.5s(.0229) = 3.3
.01146s = 3.3
s = {{{3.3/.01146}}}
s = 288 km/hr
