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?
