Your friend provides a solution to the following problem. evaluate her solution. the problem: jim (mass 50 kg) steps off a ledge that is 2.0 m above a platform that sits on top of a relaxed spring of force constant 8000 n/m. how far will the spring compress while stopping jim? your friend's solution: (50kg)(9.8m/s2)(2.0m)=(1/2)(8000n/m )x x=0.25m

The compress of the spring is 0.495.

Explanation:

Given that,

Mass = 50 kg

Spring constant = 8000 N/m

height = 2.0 m

We need to calculate the compress of the spring

Using law of conservation of energy

Where, m = mass

g = acceleration due to gravity

h = height

k = spring constant

x = distance

Put the value into the formula

Hence, The compress of the spring is 0.495.
