As shown in the figure, a 0.570 kg object is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the object travels along a frictionless, horizontal surface to point A, the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The speed of the object at the bottom of the track is vA = 13.0 m/s, and the object experiences an average frictional force of 7.00 N while sliding up the track.   (a) What is x? __ m (b) If the object were to reach the top of the track, what would be its speed (in m/s) at that point? __ m/s (c) Does the object actually reach the top of the track, or does it fall off before reaching the top? reaches the top of the trackfalls off before reaching the top     not enough information to tell
