What is the velocity of an object that has been in free fall for 1.5s?
a. 150 m/s downward
b. 6.5 m/s downward
c. -6.5 m/s downward
d. 15 m/s downward

D. 15 m/s downward

Explanation:

v = at + v₀

v = (-9.8 m/s²) (1.5 s) + (0 m/s)

v = -14.7 m/s

Rounded to two significant figures, the answer is D, 15 m/s downward.

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

overcharge is the right answer system
