Question 2 (2 points) A marble dropped from the Foshay Tower in Minneapolis hits the ground at 52 m/s. How high is the Foshay tower?

Height of the Foshay tower is 138 m

Explanation:

Using the third equation of uniformly-accelerated motion under gravity:

v² = u² + 2gh

Where v is final velocity,

u is initial velocity,

g is acceleration due to gravity,

and h is height

v = 52 m/s;

u = 0 (since the marble was dropped from rest at a height above the ground);

g = 9.8 m/s²,

h = ?

(52 m/s)² = 0 + 2 × 9.8 m/s² × h

2704 m²/s² = 19.6 m/s² × h

h = 2704 m²/s² / 19.6 m/s²

h = 138 m

Therefore, height of the Foshay tower is 138 m

[ answer ]

foliated

[ explanation ]

foliation forms in a rock when pressure squeezes the rock together. the rock then has a design of many different color little lines. there are three types of foliated rock. the types are slate, schist, and gneiss. each type of foliated rock is different based on grain size and foliation characteristics. the lines appear when the rock has been under pressure.
