Hope this helps.

Answer 2

❕❗The amount of time it spends in the air is called the time of flight. If the ground from which the projectile is launched is level, the time of flight only depends on the initial velocity v0, the launch angle θ, and the acceleration due to gravity. The unit for the time of flight is seconds (s).❕❗   #HOPE IT HELPS YOU ♠♣♥❤⭐✨✌  #GO_π_FOLLOW_ME⏪⏬⏫⤵⤴  #Itz$hwetlana..☢✳⚛☣✴❇
