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
