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
