Aspring is compressed 0.035 m inside a dart gun. (k=500 n/m). the spring has elastic energy. calculate it.

Ametal ball with a mass of 0.028 kg is dropped from rest at a height of 1.0 meters above the ground. assuming the energy in the ball is conserved, how much kinetic energy will the ball have when it is 0.5 meters above the ground?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

The solid that is formed and usually sinks to the bottom of a solution is the
