Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity The object is called a projectile, and its path is called its trajectoryThe motion of falling objects, as covered in ProblemSolving Basics for OneDimensional Kinematics, is a simple onedimensional type of projectile motion in which there is no horizontal movementIf you look at this previous video where we plotted displacement versus time, you see after 2 seconds the ball went from being on the ground or I guess the thrower's hand all the way to its peak height And in the next 2 seconds, it took that same amount of time to go back down to the ground, which makes senseFor the coin, find (a) the maximum height reached, (b) its position and velocity 400 s after being released, and (c) the time before it hits the ground 18 A soft tennis ball is dropped onto a hard floor from a height of 150 m and rebounds to a height of 110 m Kinetic And Potential Energy Energy Con...
