The velocity of a free-falling object is given by V = V2gh where h is the distance (in feet) the object has fallen and g is acceleration due to gravity (in feet per second squared). The value of g depends on your altitude. If an object hits the ground
with a velocity of 25 feet per second, from what height was it dropped in each of the following situations?
15
34. You are standing on the earth so g = 32 ft/s?
35. You are on the space shuttle, so g = 29 ft /s?
16
17
36. You are on the moon, so g =0.009 ft/s?

=−x2+2x−8

Step-by-step explanation:

2(x−4)−x2

Distribute:

=(2)(x)+(2)(−4)+−x2

=2x+−8+−x2

=−x2+2x−8
