Acceleration and magnitude of contact force

AI Thread Summary
The two-block system, with masses m1 = 4.00 kg and m2 = 3.00 kg, experiences a constant force F = 9.00 N applied to m1. According to Newton's 2nd Law, the total mass of the system is 7.00 kg, resulting in an acceleration of 1.29 m/s². To find the contact force between the blocks, the force acting on m2 must be calculated, which is equal to m2 multiplied by the acceleration, yielding a contact force of 3.87 N. The analysis confirms that both blocks accelerate uniformly due to the applied force. Understanding these dynamics is crucial for solving similar physics problems involving contact forces and acceleration.

Two blocks of masses m1 = 4.00 kg and m2 = 3.00 kg are placed in contact with each
other on a frictionless horizontal surface. A constant force F = 9.00 N is applied to the
block of mass m1. a) Determine the magnitude of the acceleration of the two-block
system. b) Determine the magnitude of the contact force between the two blocks.

You haven't put anything in sections 2 or 3 of the template.

Hint for part a) what does Newton's 2nd Law say about the acceleration of the system?

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...
