Thank you for the opportunity to help you with your question!

Relevant equations Δd=V(Δt) + 1/2 (a)(Δt)^2 3.
I have found the time using the quadratic equation for part a which is 0.36s, but I am stuck on part b. I do not understand how to do it. It seems like Δd is the same in both parts. How in hell do I find Δt for part b.

Please let me know if you need any clarification. I'm always happy to answer your questions.
