Answer: 0.04139m
Explanation:
First, we need to calculate the weight of the man which will be:
Weight = mass × acceleration due to gravity
Weight = mg
Weight = 92.5 × 9.8
Weight = 906.5N
Then, we calculate the force which will be:
F = kx
mg = kx
x = mg/k
x = 906.5/21900
x = 0.04139m.
The spring stretched for 0.04139m.
OK think of it distance,The smaller the distance less momentum is needed the Longer the distance the the longer the momentum is needed.
And The Answer Is quite easy their was no reason to be asked
Answer:1.0meter
