3) A dart of mass m=0.1kg is compressed against a spring to half of its unstretched length on a horizontal surface. It is released at rest from the compressed spring then hit a wood block of 0.2 kg mass that is at rest. The dart gets into the block and they move together along an inclined surface of angle θ. Assume all surface are frictionless. Find the maximum height the block and dart together can go up on the inclined surface. Assume the unstretched length of the spring is L=12.0cm and the spring constant is k=1000.0mN.
