For items 1 and 2, consider an 800-g ball, tied to a 1.300 m inextensible cord, and is released from rest at position 1 until it reaches position 2 just before the cord becomes taut. The ball acquired a speed of 4.90 m/s just before the cord becomes taut (at position 2), as shown in the figure.

Question
What is the net impulse exerted by the weight onto the ball during the ball’s motion from position 1 to position 2? What is the net impulse exerted on the ball during this state of impulsive motion (i.e., during the period when the cord suddenly becomes taut; position 2 to position 3)?
