A spring (with spring constant k=45 N/m) is compressed by 0.2 meters. A 0.5 kg ball is placed on top and the spring is released in a perfect energy transfer. How
high will the ball go? (show your work and conservation of energy equations)

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
