In an arcade game a 0.144 kg disk is shot across a frictionless horizontal surface by compressing it against a spring and releasing it. If the spring has a spring constant of 164 N/m and is compressed from its equilibrium position by 7 cm, find the speed with which the disk slides across the surface.

The speed with which the disk slides across the surface is 2.36 m/s.

Explanation:

 Given that,

Mass of the disk, m = 0.144 kg

Spring constant of the spring, k = 164 N/m

The spring is compressed from its equilibrium position by 7 cm or 0.07 m

We need to find the speed with which the disk slides across the surface. It is a case of conservation of energy in which the energy of the spring is gained by its kinetic energy. It is given by :

v is speed of the disk.

So, the speed with which the disk slides across the surface is 2.36 m/s.

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).
