22. kerry klutz drops her physics book off her aunt’s high rise balcony. it hits the ground below 1.5 s later. a. with what speed does it hit? b. how high is the balcony (ignore air drag).

A). Gravity makes falling objects fall 9.8 m/s faster every second.
After 1.5 seconds, it's falling at (1.5 x 9.8) = 14.7 m/s .

b). The average speed of the physics book is (1/2) (0 + 14.7) = 7.35 m/s .

Falling at an average speed of 7.35 m/s for 1.5 seconds,
the book falls

(1.5 x 7.35) = 11.025 meters 

Iwould sure like to answer your question but i honestly just don’t know

Biased means unfair but that's all ik
