Newtons 2nd Law just need to get started

AI Thread Summary
To determine the strength of the rope needed to tow a 2,270kg truck, the key is to calculate the tension based on the truck's acceleration. The time of 12 seconds is crucial as it helps find the acceleration using the initial and final velocities. The acceleration is not 3.00 m/s, as that is a velocity, not an acceleration unit. Once the correct acceleration is calculated, it can be applied to Newton's second law (F=ma) to find the required tension in the rope. Understanding these concepts allows for solving the towing problem effectively.

Problem : A car is to tow a 2,270kg truck with a rope. How strong should the rope be so that it will not break when accelerating the truck from rest to 3.00 m/s in 12.0 seconds?


So I assume it wants me to find the tension?...but the 12 seconds is throwing me off...I'm not sure what that has to do with anything if sum of the forces = ma (F=ma)...so where does the time come into play...?

You can use the time to find the acceleration. You have the initial and final velocity there if you noticed.
 
ahh silly me...i was fooled by the word 'accelerating' and thought the acceleration was 3.00 m/s...i should have noticed it wasn't even in the right units to be acceleration...ok, i have the initial velocity and final...thanks for the jump start i needed
 
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...
