**TL;DR Summary:**I need help with solving a kinematics problem, thanks!

Brynn is standing on a balcony that is 40 m above the ground. She is surprised by a pigeon and throws a flower pot up in the air. It takes 3.5 s for the flowerpot to smash to the ground below. The flower pot experiences acceleration due to gravity of 9.8 m/s2[down]. Determine the initial velocity of the flower pot when Brynn released it and how fast the flowerpot was moving just before it smashed to the ground.

This question has been confusing me for a long time. I solved for the inital velocity by using delta d = v1xt + 1/2at^2, and using 3.5 seconds as time, acceleration as -9.8 and delta d as -40 meters. The answer I got was -5.7 m/s [up] but it confuses me because can the acceleration upwards be less than the acceleration downwards? And I'm not sure if my answer is correct. Could someone help correct me? Thank you so much.
