AI Thread Summary
To calculate the velocity of a 0.160-kg hockey puck initially moving at 2.98 m/s after applying a 24.0 N force to the right for 0.055 seconds, the impulse-momentum theorem can be utilized. The change in momentum is determined by multiplying the force by the time, which is then added to the initial momentum to find the final velocity. Conversely, applying a 12.5 N force to the left for the same duration will decrease the puck's velocity, requiring a similar calculation to determine the final speed. The discussion emphasizes the importance of understanding the relationship between force, time, and velocity in a frictionless environment. Accurate calculations are essential for solving the problem effectively.

Homework Statement


A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t=0 the puck is moving to the right at 2.98m/s .

Homework Equations



Calculate the magnitude of the velocity of the puck after a force of 24.0N directed to the right has been applied for 5.5×10−2s .
If instead, a force of 12.5N directed to the left is applied from t=0 to t= 5.5×10−2s , what is the magnitude of the final velocity of the puck?

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...
