A falling iPad takes 0.15 s to travel past a window 2.7 m tall. From what height above the top of the window did the mobile device fall?
What equation would I use for this?
mr johnsons class...no one can figure this outttttttt :(
trolololol
To solve this problem, we can use the equations of motion relating to freely falling objects. In this scenario, the iPad is falling vertically, so we can use the equation:
s = ut + (1/2)at^2
Where:
- s is the distance fallen (unknown)
- u is the initial velocity, which is 0 since the object starts from rest
- t is the time taken (0.15 s in this case)
- a is the acceleration due to gravity (9.8 m/s^2, assuming no air resistance)
Since we are interested in finding the height the iPad fell from above the top of the window, let's consider the vertical displacement from the top of the window to the height above it as h. Therefore, the equation becomes:
h + 2.7 m = (1/2)(9.8 m/s^2)(0.15 s)^2
Now we can solve this equation to find the value of h.
