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

1. A car driving at a constant speed of 75 ft/s passes a police car that is initially at rest. If the police car decides to give chase

A) What rate would the police have to accelerate to catch up with the other car in 12 seconds?

B) What is the police car's speed at the end of the 12 seconds?

2. Relevant equations

Use Kinematic Equations

3. The attempt at a solution

My first step was to assign the variables:

Vo = 0

V = 75 ft/s

a = unknown

x = unknown

t = 12

I used V = Vo + at so 75 ft/s = 0 + a12 which comes out to 6.25 ft/s Is this part right, or am I way off? I'm new to Physics, so please be nice. I want to do well :) If part A is correct, I have no clue how to solve part B. Help would be greatly appreciated.
