A spring (80 {\rm N/m}) has an equilibrium length of 1.00 {\rm m}. The spring is compressed to a length of 0.50 {\rm m} and a mass of 2.1 {\rm kg} is placed at its free end on a frictionless slope which makes an angle of 41 ^\circ with respect to the horizontal. The spring is then released

    (1) I do not understand the meaning of your
    {\r and ^\circ symbols.
    (2) What is your question?
    (3) The subject is physics, not physic
    (4) Use conservation of energy to solve the problem, if it is how high the mass goes up the slope.
