Part A An unusual spring has a restoring force of magnitude F (2.00 Nm)x 00 N/m2)x 2, where x is the stretch of the spring from its equilibrium length. A 3.00-kg object is attached to this spring and released from rest after stretching the spring 1.80 m. If the object slides over a frictionless horizontal surface. how fast is it moving when the spring returns to its equilibrium length? O 2.60 m/s O 1.30 m/s O 2.97 m/s 2.23 m/s O 1.86 m/s Submit My Answers Give Up Continueanswer only if you know it

    Engineers have invented a new kind of spring whose restoring force is proportional to the third power of displacement: |F(x)| = |βx3| where B = (1/9) N/m3. One end of this spring is fixed to the bottom of an inclined plane which makes an angle θ = 36.87° with respect to the horizontal, and the other end is stretched up the incline and attached to a block of mass m = 3.00 kg. The spring is initially stretched a distance...
