Answer:
0.45 second
Step-by-step explanation:
The number of seconds it takes a dropped object to fall d feet on Earth is given as:
E(d)=0.25√d
the number of seconds it takes a dropped object to fall d feet on the sun is given as:
S(d)=0.2⋅E(d)
Therefore
S(d)=0.2 × 0.25√d = 0.05√d
Given that it take a dropped object to fall 80 feet on the sun (i.e d = 80 feet), to calculate the time in seconds we use:
S(d) = 0.05√d
S(d) = 0.05 × √80 = 0.05 × 8.944 ≈ 0.45 s
It takes 0.45 second for a dropped object to fall 80 feet on the sun
