firstly i am new here so be nice please

the problem i have is that i am stuck on a question in my assignment which is

a bullet of mass 0.6kg is fired vertically upwards by a vertical propelling force of 50N over a time scale of 0.5 seconds . calculate

1)the velocity of the bullet ehen it leaves the gun. ( the answer i have for this is based on a=f^m ie 50^0.6 giving a= 83.3 ms-2 then using V=U+AT therefore v=0+83.3X0.5 getting the final answer of V= 41.65ms-1) can you just confirm if i am on the right lines with this first

2) The Height reached by the bullet ( again i have attempted this by reaaranging v^(2)=u^(2) +2as for s to get 10.4125m)

3) The time taken from the bullet leaving the gun to its return to the same height ( i am stumped at to were to start with this one i know that gravity is going to have its effect on the return and that that will be related to the above height answer)

My main issue is that dispite getting what look to be answers to my questions i keep doubting/questioning myself

any help would be appreciated i am not looking for you to give me the answers just some guidence would be more than helpfull

many Thanks
