Answer:
Correct answer: V = 78.07 m/s
Explanation:
We can solve this problem combined with the help of kinetics or with energy conservation laws.
The first way is:
This is a free fall with no initial speed (velocity)
The formula for this case is: V² = 2 g h , we will take that g = 10 m/s²
We must first convert the ft into meters
The relationship is 1 ft = 0.3048 m, according to this 1,000 ft = 304.8 m which is also the height of the fall h = 304.8 m
V² = 2 · 10 · 304.8 = 6,096 => V = √6,096 = 78.07 m/s
V = 78.07 m/s
Otherwise it cannot be solved because we do not have a mass of parachute jumper.
God is with you!!!
