A stick of length 1.5 m and mass 8.0 kg is free to rotate about a horizontal axis through the center. Small bodies of masses 7.0 and 4.0 kg are attached to its two ends. The stick is released from the horizontal position. What is the angular velocity of the stick (in rad/s) when it swings through the vertical? (Enter the magnitude.)
A stick of length 1.5 m and mass 9.0 kg is free to rotate about
a horizontal axis through the center. Small bodies of masses 8.0
and 2.0 kg are attached to its two ends (see the following figure).
The stick is released from the horizontal position. What is the
angular velocity of the stick (in rad/s) when it swings through the
vertical? (Enter the magnitude.)
Q21 (15 points): A uniform rod of mass m 1.5 kg and length d- 2.0 m is supported by a pivot point P at its top and is free to rotate iın the vertical plane. A block of mass m2 0.8 kg is attached to the other end of the rod. The rod-block system is initially at rest, and a 1g bullet is fired horizontally into the rod through a point x 08 d below the pivot P Assume that...
1) Rall Gun". A metal bar with mass of 2 kg., 1.5 m long and having a resistance of 10 Ω rests horizontally on wires of a unclosed circuit comprising a 120V DC power supply connected in series with a 25 Ω resistor and a switch in a uniform magnetic fleld of 1.6 T orthogonal to the plane of the circuit. What is the acceleration of the bar right after the switch is closed?

A long wooden post is suspended horizontally by a rope attached
to the ceiling at distance Δx = 1.20 m from the end. A pylon
supports the other end as shown below. The 5.70 m long post is
uniform along its length and has a mass of 35.5-kg. A 10.0-kg mass
is suspended at a distance Δx = 1.20 m from the other end. (a) Find
the tension in the rope in N. (b) Find the force that the pylon...
A 1.2 m long thin rod is pivoted to rotate <!- out an axis 15 cm from the end. If the rod's mass is 250 g, what is the moment of inertia of the thin rod about this, horizontal.axis? the correct answers 0.0806 kg*m^2 show why and how
