1. A wooden rod of length 40.0 cm and mass 1.00 kg is sitting on a frictionless horizontal surface. The rod has a pin through its centre so that it can freely rotate about a vertical axis perpendicular to the rod and passing through the center of the rod. A projectile of mass 0.0100 kg is now shot at the rod. The projectile is moving horizontally with a speed of 2.00 x 102 m/s in the direction perpendicular to the...
Please provide an explanation of how you got your answer so I can understand the problem. Chapter 15, Problem 092 A grandfather clock has a pendulum that consists of a thin brass disk of radius r 13.61 cm and mass 1.065 kg that is attached to a long thin rod of negligible mass. The pendulum swings freely about an axis perpendicular to the rod and through the end of the rod opposite the disk, as shown in the figure. If...
Please solve this question, and show steps. Thank you so much. A uniform rod is set up so that it can rotate about an axis at perpendicular to one of its ends. The length and mass of the rod are 0.711 m and 1.13 kg, respectively. A force of constant magnitude Facts on the rod at the end opposite the rotation axis. The direction of the force is perpendicular to both the rod's length and the rotation axis. Calculate...
please show all work so i can follow along and learn. Thank you so much! Consider the system shown below. Each horizontal rod has a linear mass density of 1 kg per meter, and each vertical rod has a negligible mass. a. What mass for object A will balance the A-B system? What mass for object C will balance the whole system? b. Use the additive nature of moment of inertia and the parallel axis theorem to calculate the total...
A uniform rod is set up so that it can rotate about a perpendicular axis at one of its ends. The length and mass of the rod are 0.847 m and 1.27 kg. What constant-magnitude force acting at the other end of the rod perpendicularly both to the rod and to the axis will accelerate the rod from rest to an angular speed of 6.37 rad/s in 9.87 s?
A uniform rod is set up so that it can rotate about a perpendicular axis at one of its ends. The length and mass of the rod are 0.803 m and 1.17 kg. What constant-magnitude force acting at the other end of the rod perpendicularly both to the rod and to the axis will accelerate the rod from rest to an angular speed of 6.49 rad/s in 8.93 s?
A uniform rod is set up so that it can rotate about a perpendicular axis at one of its ends. The length and mass of the rod are 0.825 m and 1.23 kg. What constant-magnitude force acting at the other end of the rod perpendicularly both to the rod and to the axis will accelerate the rod from rest to an angular speed of 6.77 rad/s in 9.69 s?
A large bell is hung from a wooden beam so it can swing back and forth with negligible friction. The center of mass of the bell is 0.55 m below the pivot, the bell has mass 40.0 kg , and the moment of inertia of the bell about an axis at the pivot is 20.0 kg⋅m2 . The clapper is a small, 1.8 kg mass attached to one end of a slender rod that has length L and negligible mass....
A door with mass M= 3.00 kg and width L=2.00m is hinged at one side so that it can rotate without friction about a vertical axis. A heavy bullet embeds in the 3L/4 of the door after it is fired as shown. The mass of the bullet is m=0.200kg and the initial speed of the bullet is speed 410 m/s . Part A Part complete What is the angular speed of the bullet and the door after the bullet embeds...
