Stopping a Bullet: Acceleration Explained | Dynamics

In this video, we delve into the concept of projectile motion in a resisting medium. Using the equation v = vo - kx, we explore the initial acceleration of the projectile and calculate the time it takes for the projectile to penetrate 0.325 meters into the resisting medium. Our expert instructors break down some concepts into easily digestible information, ensuring that you grasp the core principles of particle motion, velocity and acceleration. Everything else comes by analyzing the problem and the system at hand. Subscribe to our channel for more expert insights and analysis, and get ready to expand your understanding and expertise. Problem statement: Problem 11.16 (Beer, Johnston, Cornwell, Self) A projectile enters a resisting medium at x = O with an initial velocity vo= 900 m/s and travels 1/3 m before coming to rest. Assuming that the velocity of the projectile is defined by the relation v = vo- kx, where vis expressed in m/s and xis in m, determine (a) the initial acceleration of the projectile, (b) the time required for the projectile to penetrate 0.325 m. into the resisting medium. Answer: a) -2.43 * 10^6 m/s^2 b) 1.37 ms In this video: 00:04 Initial acceleration of the projectile 02:06 Time when the position is 0.325 06:43 Another way to solve the letter b 07:27 Final toughts 🎓 Can you trust the answers and solutions provided? Well, you never should trust anything 100%. Make sure you are checking for yourself. When I’m solving the questions, I always solve on my own and then check the results against other sources. If there is divergence, I look for more sources. So while I can’t promise you everything will be 100% correct, I can promise I’ve done my due diligence before posting.
