Hello! Could someone please help me answer this question, showing and explaining all your work in as much detail as possible. Thank you so much!

4. A potato gun has a barrel that is 0.8 m long. It uses compressed air to push a potato with constantacceleration until it leaves the barrel.(a) If the gun provides 160 m/s2 of acceleration over this distance, how fast does the potato leave thegun?(b) If the gun is angled at 30 above the horizontal, what are the horizontal and vertical componentsof the potato's final velocity?(c) What is the speed of the potato at the peak of its trajectory?
