A projectile is fired with an initial speed of 28 m/s and has a maximum upward vertical displacement from its launch position of 4.4 m. What angle above the horizontal is the projectile launched at?
A projectile has an initial speed of 25 m/s and is fired at an angle of above the horizontal. What is the time between the projectile leaving the ground and returning to the ground at the same height that it was launched from?
The change in the vertical displacement of a projectile from its launch position and its horizontal displacement from its launch position is shown in the graph. Which of the following graphs most correctly represents how the mechanical energy of the projectile changes from the instant that it is launched to the instant that it lands?
