Calculating work for different springs calculate the work required to stretch the following springs 0.5 m from their equilibrium positions. assume hooke’s law is obeyed. a. a spring that requires a force of 50 n to be stretched 0.2 m from its equilibrium position. b. a spring that requires 50 j of work to be stretched 0.2 m from its equilibrium position.

Part a)

U = 31.25 J

Part b)

U = 312.5 J

Explanation:

Part A)

A spring that requires a force of 50 N to be stretched 0.2 m from its equilibrium position.

So here we have

k = 250 N/m

now the energy stored in the spring is given by

Part B)

A spring that requires 50 J of work to be stretched 0.2 m from its equilibrium position.

So here we know the formula of spring energy as

now by the formula of energy stored in spring

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

pls mark as brainliest.

graph question answered .. you think better when you are relaxed and happy
