AI Thread Summary
To find the average speed of the caiman, first calculate the total distance, which is 160 meters plus 310 meters, totaling 470 meters. Next, determine the time taken for each segment: 16 seconds for the first 160 meters at 10 m/s and 77.5 seconds for the 310 meters at 4 m/s, resulting in a total time of 93.5 seconds. The average speed is then calculated by dividing the total distance by the total time, yielding an average speed of approximately 5.03 m/s. This problem illustrates the importance of understanding average speed calculations in varying conditions. The solution emphasizes the need for careful time and distance analysis in speed-related problems.

need help ASAP- Average Speed--Interval Problem

Average Speed--Interval Problem

Question: A caiman swims 160 meters at a speed of 10 m/s. It then enters a stream and slows to 4 m/s for 310 meters. What is the average speed of this cousin of the crocodile?

Equation given: Average speed is total distance divided by total 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...
