Aship drops anchor in a harbor. the anchor is 49 ft. above the surface of the water when it is
creased. use the vertical motion formula h=-161? + vt + s to answer the following questions.
a. what is the value of x, the starting height?
b. what is the value of h when the anchor hits the water?
c. the starting velocity is zero. after how many seconds will the anchor hit the water?

Step-by-step explanation:

h = -16t² + vt + s

v is the starting velocity, and s is the starting height.

a. The starting height is 49 feet.

s = 49

b. When the anchor hits the water, the height is 0.

h = 0

c. Plug in values:

0 = -16t² + 0t + 49

0 = -16t² + 49

16t² = 49

t² = 49/16

t = 7/4

-14 is the answer

hope this : ))

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
