There is a block, call is mass 1 of 1.2kg. It is being compressed 75 mm into a spring with a k value of 450 N/m that is elevated 1.2m above 0 (refer to the diagram). After it is released, it travels down a ramp and encounters a "rough patch" of ramp for 25cm with a coefficient of friction of 0.11. Mass 1 then gets to 0 level and undergoes a perfectly inelastic collision with Mass 2 (m2= 2.3kg). Solve for the speed that radar gun placed after the collision tell you the speed of the block are?
