Accepted Answer
The ball in the air is for 0.319 sec.The horizontal pace of a projectile is regular (in no way converting in value), and there's a vertical acceleration because of gravity; its cost is 9.8 m/s/s, down, The vertical speed of a projectile changes via nine.8 m/s every second, The horizontal motion of a projectile is impartial to its vertical movement.Projectile motion is a form of motion experienced with the aid of an object or particle that is projected in a gravitational field, such as from Earth's floor, and movements alongside a curved route below the action of gravity best.Projectile motion is the movement of an object thrown (projected) into the air. After the initial force that launches the item, it most effectively reports the pressure of gravity. The object is known as a projectile, and its route is called its trajectory.Calculate:-H = ut + 1/2 gt²Since the vertical initial velocity is 0.H = 0 +gt²t = [tex]\sqrt{ \frac{H}{g}[/tex] = [tex]\sqrt{ \frac{1}{9.8}[/tex] = 0.319 sec.Learn more about projectile motion here:-https://brainly.com/question/10680035#SPJ4
