The 3.25-kg collar shown below is attached to a spring and released from rest at A. The collar then travels downward a distance of y = 1.00 m . The spring has a spring constant of k = 26.00 N/m . The distance a is given as 1.10 m . The datum for gravitational potential energy is set at the horizontal line through A and B. Part A - Velocity of the Collar at C without Friction Determine the magnitude of the velocity of the collar at C when the effects of friction are neglected. The spring is initially unstretched when the collar is at A. Part B - Average Frictional Force Acting on the Collar Determine the magnitude of the average friction force exerted on the collar when the velocity of the collar at C is 2.78 m/s . The spring is initially unstretched when the collar is at A. Part C - Average Frictional Force Acting on the Collar Determine the magnitude of the average friction force exerted on the collar when the velocity of the collar at C is 2.78 m/s and the spring has an unstretched length of 0.60 m.
