Answer:
Acceleration, [tex]a=23\ m/s^2[/tex]
Explanation:
Given that,
The statue of Liberty is at a height of 46 m.
Jean Grey needs to fly from rest on the ground to the top of the Statue of Liberty (46 m) in 2.0 seconds.
We need to find her minimum average acceleration during her ascent. Let it is t. Using the second equation of motion to find it.
[tex]h=ut+\dfrac{1}{2}at^2\\\\h=\dfrac{1}{2}at^2\\\\a=\dfrac{2h}{t^2}\\\\a=\dfrac{2\times 46}{(2)^2}\\\\a=23\ m/s^2[/tex]
So, the constant acceleration is [tex]23\ m/s^2[/tex] for the entire distance.
