1. A block of mass m = 10 Kg is at rest on the inclined plane seen at figure 1. The coefficient of static friction between the block and the plane is µ, = 0.5 N/Kg. The block of mass m is pulled by a force F =100 N through a spring of force constant k = 0.3 as seen in figure 1. The block is pushed against a spring, compressing it. Determine the speed of the block after the block is released (g = 10 m/s²). k
