A 800 g. 40-cm-long metal rod is free to rotate about a frictionless axle at one end

A 800 g. 40-cm-long metal rod is free to rotate about a frictionless axle at one end. While at rest, the rod is given a short but sharp 1000 N hammer blow at the center of the rod, aimed in a direction that causes the rod to rotate on the axle. The blow lasts a mere 1.7 ms. 


Part A 

What is the rod's angular velocity immediately after the blow?

    Review A 76 g , 40-cm-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 11 g ball of clay traveling horizontally at 2.2 m/s hits and sticks to the very bottom tip of the rod. A) To what maximum angle, measured from vertical, does the rod (with the attached ball of clay) rotate? Express your answer to two significant figures and include the appropriate units.

    Problem 10.30 A uniform 2 kg solid disk of radius R = 0.4 m is free to rotate on a frictionless horizontal axle through its center. The disk is initially at rest, and then a 10 g bullet traveling at 500 m/s is fired into it as shown in the figure below. If the bullet embeds itself in the disk at a vertical distance of 0.2 m above the axle, what will be the angular velocity of the disk? Express...

    A student sitting on a stool that is free to rotate (frictionless), but is initially at rest, holds a bicycle wheel.  The wheel has a rotational velocity of 10 rev/s about a vertical axis counter clockwise (vector of angular momentum points up).  The rotational inertia of the wheel is 4 kg*m2 about its center and the rotational inertia of the student and wheel and platform about the rotational axis of the platform is 12 kg*m2. If the student flips the axis of...

    A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
