Physics

A horizontal spring with a spring constant of 190 N/cm iscompressed 6.3 cm. A wooden block with a mass of 1.5 kg is placedin front of and in contact with the spring. When the spring isreleased it pushes the block, which slides on a frictionlesshorizontal surface for some distance. The block then slides up africtionless incline of 27ï‚° above the horizontal and comes to amomentary stop before sliding back down. The system is the spring,the block, the incline, and the Earth. Ignore air resistance. A)Sketch the situation and label all variables for: i. the spring andblock before the spring is released ii. the block sliding on thehorizontal surface iii. the block sliding up the incline B) Listall known quantities. C) Draw the free body diagram for the blocksliding up the incline. D) What is the potential energy of thespring before it is released? E) What is the kinetic energy and thespeed of the block as it slides on the horizontal surface after thespring has pushed it? F) At what height does the block stop on theincline? G) If the incline were rough, how would the stoppingheight of the block compare to the stopping height when the inclineis frictionless? Explain using energy.
