A 50 g dart rests up against a spring that has been compressed 0.04 meters. It has a spring constant of 1560 N/m. What is the maximum velocity of the dart after the spring has transferred all its energy to it.

The maximum velocity of the dart after the spring has transferred all its energy to it is 7.06 m/s.  

Explanation:

Given that,

Mass of the dart, m = 50 g = 0.05 kg

Compression in the spring, x = 0.04 m

Spring constant, k = 1560 N/m

We need to find the maximum velocity of the dart after the spring has transferred all its energy to it. The kinetic energy is converted to elastic potential energy as :

So, the maximum velocity of the dart after the spring has transferred all its energy to it is 7.06 m/s.

d) physical means can be used to separate the components of air.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
