Calculating the time required for the cooking robot to flip an object

[Persona]

Hi, i have calculated the time required for the cooking robot to flip an object as you can see from the attached file, however, the time result that i got was about 0.2 second which 's a bit small. So I'm wondering whether my calculating method is correct or not.
Also, please note that i assumed no drag and friction.
Appreciate your help
Thank you so much,
Samuel

From the video, the estimated time require to flip the meat weight 100g usually takes about 0.4 second.
