1. When the 2 kg block passes point A shown, its upward velocity is 4 m/s. Determine the highest point that the block reaches, measured as the distance from point A along the inclined plane. Also determine the maximum deformation of the spring of constant 100 kN/m when it momentarily arrests the block when it travels down the inclined plane. Assume that there is no friction between the block and the slope. Also neglect the size of the block.
