Solution This question,Where did 1 / 3ML ^ 2 come from? I dont understand.Can you explain in detail?How did we get that number?Why didn't we use 1 / 12ML2? Q18 (15 points): A paintball gun is fired at a rod of total length L-40 cm and mass M-210 g. The rod is fixed from one end and can freely rotate without friction. The ball hits the rod and sticks to it, so that the ball+rod system starts rotating. What is...
Q19: The uniform rod of mass M- 2 kg and length of L- 8 cm is free to rotate about a horizontal axis shown in the figure. An object of mass 0.4 kg moving with 24 m/s strikes and then sticks to the initially stationary rod as shown. If rotational inertia of the rod according to its center of mass is given as Icmdisk M, find the a) rotational inertia of the system before and after collision, b) angular speed...
Q17 (15 points): As shown in the figure, a 5.00 g bullet is fired into a 920 g block attached to the end of a 75.0 cm uniform rod of mass 350 g. The block-rod-bullet) system then rotates in the horizontal plane of the figure, about a fixed axis at A. Treat the block as a point particle. a) Calculate the rotational inertia of the (block-rod-bullet; system about point A b) If the angular speed of the system about point...
The assembly shown in the figure below consists of a thin rod of length l = 23.9 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when it starts to rotate clockwise. (a) After the combination rotates through 90...
Homework 51. (III) A thin rod of mass M and length l rests on a friction- less table and is struck at a point l/4 from its CM by a clay ball of mass m moving at speed v (Fig. 11-39). The ball sticks to the rod. Determine the translational and rotational motion of the rod after the collision. FIGURE 11-39 Problems 51 and 84. Homework 34. (1) Calculate the angular momentum of a particle of mass m moving with...
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...
Part A is completed (0.205). I need parts B and C (circled in yellow). Incorrect answers which I tried are circled in red (6%) Problem 16: A rod of niass M-3.05 krt and length L can rotate about a lunge at sts left end and is initially at rest. A putty ball of mass m5s g, moving with speed v 6.86 m/s, strikes the rod at angle 0- 39 from the normal at a distance D 23 L, where L...
