Please answer this Physics question.

3. A spring with spring constant it = 30.0 Nl is at the base of a frictionless plane inclined at an angle 8 : 30.0\" above the horizontal. An object with mass m is placed against the spring= compressing it to 31,; = ['}.35('] In from its equilibrium position. The object is then released and travels a distance of (I = 0.150 111 along the inclined plane. (a) \"That was the object's mass? (b) The object then slides back down and reconlpresses the spring. How far away from its equilibrium position is the spring compressed? (c) If, instead, there was friction, and that the work done by the friction was ['}.825 J. how far from its equilibriuln position is the spring now compressed? Take 9 = 9.81 InXs2 and show all your work
