Magnitude and direction problem

AI Thread Summary
To solve the problem, first determine the acceleration of the object by calculating the change in velocity over time, using the initial and final velocities. The acceleration can be found by breaking down the velocities into x and y components, given the angle of 29.1 degrees. Once the acceleration is known, apply Newton's second law (F = ma) to find the magnitude and direction of the force. The force will also need to be expressed in terms of its components to account for the two-dimensional motion. This approach will yield the required magnitude and direction of the force applied during the object's motion.

Homework Statement


A 1kg object is moving in the x direction at 15.6 m/s. Just 3.4s later, it is moving at 32.4 m/s at 29.1 degrees to the x axis. What are the magnitude and direction of the force applied during this time?


Homework Equations





The Attempt at a Solution


I really don't know where to start. Can anyone help by providing an equation and solution?

The solution will have to come from you. Start by using the given quantities to find the acceleration of the object. Assume that the acceleration is constant. The starting equation is the definition of acceleration in terms of velocity. This is in two dimensions so you have to use x and y components.

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...
