I need help with this problem using the kinematic equations. My professor gave me the answer to this problem and wants to know the steps to achieve this answer.(adsbygoogle = window.adsbygoogle || []).push({});

This is the example:

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of -5.60 m/s^2 for 4.20 s, making straight skid marks 62.4 m long ending at the tree. With what speed does the car then strike the tree?

The professor's answer is:

The speed is 3.10 m/s.

Thank you in advance for taking the time to help me!
