The spring has a spring of 240 n/m how much potential energy is stored in the spring as it is stretched 0.20

You get 6 for mechanical

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second

Answervery high orbital velocities in a very compact region;

What happens is they connect and there
