A 15 kg block is released from the point A with an initial speed of 10 m/s as shown in figure. The track is frictionless except for the portion between points B and spring, which has a length of 100 m. The block travels down the track, hits a spring with spring constant of 2 N/m. The coefficient of static friction and kinetic friction between the block and the surface is 0.8 and 0.2, respectively. a) Find the speed of the block when it reaches the point B? b) Determine the compression of the spring due to the block. c) After stopped by spring, will the block moves again or not?

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

your answer is, orbit around the nucleus
