Chris is on top of a mountain 120 feet above the ground shooting a bow and arrow. He shoots the arrow at an initial velocity of 128 feet per second. The equation that can be used to model the path of the arrow
is = −16! + 128 + 120, where y is the height of the arrow above the ground, in feet, and t is the time, in seconds, since the arrow has been shot.

A) After 2 seconds what is the height of the arrow?

B) determine after how many seconds, to the nearest tenth of a second, the arrow hits the ground

answer: 88

step-by-step explanation:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
