Answer:
1.11 s.
Explanation:
From the question given above, the following data were obtained:
Height (H) = 6 m
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) =.?
The time taken for the branch to hit the ground can be obtained as follow:
H = ½gt²
6 = ½ × 9.8 × t²
6 = 4.9 × t²
Divide both side by 4.9
t² = 6/4.9
Take the square root of both side
t = √(6/4.9)
t = 1.11 s
Therefore, it will take 1.11 s for the branch to hit the ground.

the answer is c google bohj
Answer: Cannot determine cause we need to know the change of time to calculate the work.
Explanation:
m = 0.5kg
V = 3m/s - 5m/s = -2m/s
P = W/t = Fv
F = ma
W = Fvt
W = (0.5)(9.8)t = 4.9t
