A 2.3-kg fireworks shell is fired at an angle 19.5° from the vertical from a mortar and reaches a height of 31 m. Take the upward direction to be positive for this problem. 1.) negleting air resistance , calculate the shells speed in m/s when it leaves the mortar. 2.) The mortar itself is a tube .525 meters long, calculate the acceleration of the shell, in the tube as it is propelled from rest, to the speed found in part 1? 3.) What is the average net force in newton acting on the shell in the mortar?
