The problem ask to calculate the bullet's flight time and the bullet's speed as it left the barrel. So base on the problem, the answer would be that the flight time is 0.076 seconds and the speed of the bullet is 657.9 m/s. I hope you are satisfied with my answer and feel free to ask for more if you have questions and further clarifications.

Therefore, the skeletal system is a body system comprised of bone structures and tissues that give the body its shape and protects internal organs.
Hope this helps!
