Answer:
Unknown: d = ? Relevant Equation: d = vo•t + ½•a•t2. Solution: 11.2 m/s2. 3. A feather is dropped on the moon from a height of 1.40 meters.
Explanation: Given: a = 3.20 m/s2
t = 32.8 s vo = 0 m/s Unknown: d = ?
Relevant Equation: d = vo•t + ½•a•t2
Solution: d= (0 m/s)•(32.8 s) + ½•(3.20 m/s2
)•(32.8 s)2
d= 0 m + 1721 m
Answer: 1721 m = 1720 m (3 sig figs)
