Kenny klutz drops his physics book off his aunt's high-rise balcony.it hits the ground below 1.5 s later? b. how high is the balcony ? ignore air drag.

Question

 nothing

Answer 1

We an use kinematics in one dimension to solve for the distance the book falls, which would be the height.

 

d = ?

t = 1.5 seconds

a = 9.8 m/s² (acceleration of gravity)

 

d = v_it + 1/2 a t²

Since he dropped the book, v_i = 0

 

So d = 0 + 1/2 (9.8) (1.5)²

 

Now solve for d and this will give you the distance it fell (or the height of the balcony)
