he two thin rods shown below are initially laying on a smooth horizontal table. They each have a mass of 7 kg and a length of 1 m. The blue rod moves towards the red rod (which is stationary) with the velocity and angular velocity given below before they collide. Immediately after the collision, the two rods become permanently stuck together as illustrated on the right side of the figure. Assuming both linear and angular momentum are conserved during the purely inelastic (e = 0) collision, determine: a) the velocity of the center of mass of the combined rods after the collision b) the angular velocity of the combined rods after the collision c) the amount of kinetic energy lost during the collision Before Collision After Collision V6,1 = 10 m/s %3D w = -5 rad/s

Figure 2 shows a ballistic pendulum consists of 5 kg slender rod and 10 kg solid cylinder. The pendulum is originally at rest, θ = 0ᵒ. A 10 g bullet with velocity v is fired to the solid cylinder.a) Determine the location of ?̅ of the center of mass G of the pendulum. Then, calculate the moment of inertia of the pendulum about an axis perpendicular to the page and passing through G.b) Initially, it is estimated that the value of v is 622 m/s. Analyze the angular velocity of the cylinder just after the bullet embedded. Also, determine the expected value of maximum angle θ will swing when the pendulum stops. Then, evaluate the expected amount of energy lost during impact in percentage.c) However, it is observed that the cylinder swing upward to a maximum angle of θ = 22ᵒ. Determine the actual initial value of v. Then, analyze the linear impulse imparted by the bullet on the cylinder. Also, evaluate the force on the rod immediately just after the impact.
