A falling iPad takes 0.16 s to travel past a window 2.1 m tall. From what height above the top of the window did the mobile device fall?
To find the height from which the iPad fell, we can use the equation of motion for freefall:
h = 0.5 * g * t^2
Where:
h is the height
g is the acceleration due to gravity (approximately 9.8 m/s^2)
t is the time taken
Given:
t = 0.16 s
g = 9.8 m/s^2
height of the window = 2.1 m
We can substitute the values into the equation and solve for h:
h = 0.5 * 9.8 * (0.16)^2
h = 0.5 * 9.8 * 0.0256
h ≈ 1.25888
Therefore, the iPad fell from a height of approximately 1.25888 meters above the top of the window.
