A physics student drops a water balloon from a second-floor window trying to hit their mean teacher. The window is 12m from the ground. How long does it take for the balloon to hit the ground?

Respuesta :

Upendo

from,

d = 1/2gt² - eqn for free falling object

12 = 1/2 * 9.8 * t²

24 = 9.8*t²

t = 1.56 s.

It will take 1.56 seconds for the balloon to hit the ground.

What is a free falling object ?

  • An object that is moving only because of the action of gravity.
  • The motion of the free falling object is described by Newton's second law of motion.
  • When an object is in free fall, the velocity of that object increases because of the the gravitational acceleration (g)

What is the equation for the free falling object?

                    d = 1/2 gt²

putting the values ,

           ∴   12 = 1/2 * 9.8 * t² ( g = gravitational acceleration = 9.8 m/s*2)

            ∴  24 = 9.8*t²

           ∴      t = 1.56 s.

Thus, It will take 1.56 seconds for the balloon to hit the ground.
