A toy dart gun has a spring with k=128 N/m. a kid pulls back on the spring with a 8.22 N force. how far does it stretch?(unit=m) PLEASE HELPPP

0.064 m

Explanation:

When a spring is stretched/compressed, the force exerted in the spring is related to the elongation of the spring by the equation:

where:

F is the force applied

k is the spring constant

x is the stretching/compression of the spring

In this problem, we have:

is the force applied by the kid on the spring

k = 128 N/m is the spring constant

Solving for x, we find how far the spring stretches:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
