Students drop a 2 kg object from rest out a window that has a height of 10 m during a lab experiment. The students time the
object to hit the ground and measure 1.2 s. Calculate the
difference between the PE at the top and the KE at the bottom.
a. greater than 75 J
b. less than 25 J
c. between 25 J & 50 J
d. between 50 J & 75 J

Bradley and kelly are out flying kites at a park one afternoon. a model of bradley and kelly's kites are shown below on the coordinate plane as kites brad and kely, respectively: kites adbr and kely are shown on a coordinate plane. the vertices of adbr are a is at 9, 1; d is at 1, 5; b is at 9, 9; and r i which statement is correct about the two kites? (1 point) they are similar because segment br to segment db is 1: 2 and segment ke to segment yk 1: 2. they are not similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 2. correct! they are not similar because segment br to segment db is 1: 2 and segment ke to segment yk is 1: 5. they are similar because segment br to segment db is 1: 5 and segment ke to segment yk is 1: 5.
