Question 4 (10 points) A mass of 2.0 kg is placed on a spring which has a spring constant of 267 N/m and compresses it a length of 72 cm from its equilibrium position. This set up is on an incline at an angle of 35* above the horizontal and there is a coefficient of kinetic friction of 0.26 between the mass and the surface. What will the speed of the mass be when it has moved a total distance of 1.5 m up the incline from its starting position. (Use g = 9.Bm/s and round answer to 1 decimal place.) Your Answer: Answer units
