Solve it asap. My last attempt. Need 100% correct answer. Multiple votes will be done...

Could I have help with this average speed and velocity problem. I already know the answers"average velocity = 2.7 m/s due east, ­average speed = 8.0 m/s"  but I need a detailed explanantion on how and why because I am not understanding and getting the same answers

Answer parts A and B

Help, I think the answer is the 5th choice, but I am not sure.

The Beretta Model 92S (the standard-issue U.S. army pistol) has a barrel 127 mmmm long. The bullets leave this barrel with a muzzle velocity of 349 m/sm/s. 1) What is the acceleration of the bullet while it is in the barrel, assuming it to be constant? Express your answer in meters per second squared. 2) What is the acceleration of the bullet while it is in the barrel, assuming it to be constant? Express your answer as a multiple of acceleration due to gravity g.   3) For how long is the bullet in the barrel? Express your answer in seconds.

a. Find the velocity v(t) and acceleration a(t). b. At what value of t does v=0? c. What is the maximum height?
