The 2.00-kg slender rod shown is hanging in a vertical position and is pin-supported at point A. The slender rod is initially at rest until a 1.000-kg block C, strikes it at its end at point B. The block slides on a frictionless surface with a velocity of 3.50 m/s to the right. After the impact, it slides with a velocity of 1.250 m/s to the right, and the bar rotates with an angular velocity, ω'. Sketch the moment-impulse diagram 1. Which of the following gives the correct kinematic relationship relating the final velocity of the center of the rod, v'G, and its angular velocity, ω'? 2. Which of the following gives the closest value of the coefficient of restitution, e, between the block and the slender rod? 3. Which of the following gives the closest value of the magnitude of the horizontal impulse at the support at point A?
