Answer:
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.
In physics, we define speed as:
speed = distance / time, or
In order for this to work properly - we need to convert 1.9 minutes into seconds. One minute is 60 seconds, nine tenths of a minute is 54 seconds. So 1.9 minutes in seconds is 60 + 54 = 114.
Now just solve the fraction.
