AI Thread Summary
To calculate the average force acting on a dummy during a crash test, the initial speed of the car is 11.6 m/s, and the dummy moves 0.81 m before coming to a stop. The mass of the dummy is 55 kg. The average force can be determined using the principles of physics, specifically by applying the equations of motion and Newton's second law. Participants in the discussion emphasize the importance of showing work and understanding the underlying concepts to arrive at the correct solution. Engaging with the problem step-by-step is crucial for effective learning and accurate calculations.

1. A set of crash tests consists of running a test car moving at a speed of 11.6 m/s (25.52 m/h) into a solid wall. Strapped securely in an advanced seat belt system, a 55 kg (121 lbs) dummy is found to move a distance of 0.81 m from the moment the car touches the wall to the time the car is stopped. Calculate the size of the average force which acts on the dummy during that time.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
