Simora [160]

Answer: 810 J

Explanation: work W = F·s = 101 N · 8.0 m = 808 J

Force F = u mg = 101 N in which u is friction constant. Also mass is included in force.

No its wrong

Correct compression is 0.41

Explanation:

After jumping from 2m height on spring attached platform platform is compressed a distance x(let).

So work done by gravity on Jim is converted into spring potential energy.

k=8000 N/m

mass of Jim =50 kg

$\frac{1}{2}k(x)^{2} =m*g(2+x)$

$\frac{1}{2}8000(x)^{2} =50*9.8(2+x)$

$8.16x^{2} =2 +x$

Solve this quadratic one solution is positive and other is negative.

positive one is our answer = 0.41 m
