Finding Magnitude of Acceleration using the force

AI Thread Summary
The discussion centers on calculating the friction force and acceleration of two locked sliding cars. The friction force was calculated to be 73,575 N using the coefficient of friction, total mass, and gravitational acceleration. To find the magnitude of acceleration, participants suggest using Newton's second law, but there is confusion about the correct formula. The acceleration can be determined by dividing the friction force by the total mass of the cars. Clarification on the appropriate formula for acceleration is requested to solve the problem accurately.

Homework Statement


Car 1: 2000 kg
Car 2: 3000 kg
coefficient of friction: 1.5
angle of movement: 40 degrees North of East
displacement of vehicles: 6.0 m

What was the friction force that acted upon the locked sliding cars to stop them?

What was the magnitude of the acceleration that this force produced on the sliding cards sliding together?


Homework Equations



Ff = coe of fric x mass x 9.81

The Attempt at a Solution



so to figure out the friction force I did:
(1.5)(2000 + 3000)(9.81) = 73575 N

but I don't know how to figure out the magnitude of acceleration!
would the formula be this? coe of fric x 9.81 ?

If that isn't the formula can someone please help me?

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...
