Lab: Ballistic Pendulum A ballistic pendulum is a device for measuring the momentum of a bullet, from which it is possible to calculate its velocity and kinetic energy. Ballistic pendulums have been rendered obsolete by modern chronographs, which allow direct measurement of projectile velocity. 1.

A ballistic pendulum is a device used to determine the speed of a bullet. Use the horizontal sliders to adjust the mass of the bullet, mass of the wood block, and the initial velocity of the bullet. Press the "Fire" button. The bullet collides with and sticks inside of the wood block. After the collision the wood block and bullet swing upward (and then back and forth). Use the vertical slider on the right to move the reference line in order to determine the maximum height reached by the bottom of the block. Use the masses of the block and bullet, the maximum height reached, and the concepts of conservation of momentum and energy to calculate the initial velocity of the bullet. Use the checkbox to show the initial velocity once you have finished your calculation and see how close you came.1. Drag the slider to set the mass of the block to 4 kg and the mass of the bullet equal to 0.075 kg. Adjust bullet speed to varying values 100, 150, 200 and 225 m/s. Click the "shoot" button to shoot the bullet at the block. Now the block, together with the bullet, goes into oscillation. Observe the height of the pendulum in the simulator. Use the program and pause function to measure the height h. Calculate the speed of the block using Vblock = [2 g h]\"2 Use the formula Vbuuet = (1 + M / ITI)'VbIock to calculate the velocity of the bullet. Enter the measurements in the table below. Obtain the percent error for the calculated value for the speed of the bullet. 953 r4939"? 999 Conclusion
