A mass of 3.0 kg is placed on a spring which has a spring constant of 253 N/m and compresses it a length of 76 cm from its equilibrium position. This set up is on an incline at an angle of 42º above the horizontal and there is a coefficient of kinetic friction of 0.13 between the mass and the surface. What will the speed of the mass be when it has moved a total distance of 2.0 m up the incline from its starting position. (Use g = 9.8m/s2 and round answer to 1 decimal place.)
