Finding Magnitude of Acceleration using the force

In summary, the conversation discusses the friction force and magnitude of acceleration between two cars with weights of 2000 kg and 3000 kg respectively, a coefficient of friction of 1.5, and an angle of movement of 40 degrees North of East. The formula for friction force is given as Ff = coefficient of friction x mass x 9.81, which results in a force of 73575 N. To find the magnitude of acceleration, Newton's second law can be used, with the formula being coefficient of friction x 9.81. The conversation ends with a request for clarification on the correct formula for finding the acceleration.

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?

Related to Finding Magnitude of Acceleration using the force

1. What is the formula for finding magnitude of acceleration using force?

The formula for finding magnitude of acceleration using force is a = F/m, where a represents acceleration, F represents force, and m represents mass.

2. How do you calculate the magnitude of acceleration?

To calculate the magnitude of acceleration, you need to divide the force applied to an object by its mass.

3. What is the unit of measurement for magnitude of acceleration?

The unit of measurement for magnitude of acceleration is meters per second squared (m/s²).

4. How does an increase in force affect the magnitude of acceleration?

An increase in force will result in an increase in magnitude of acceleration, assuming the mass of the object remains constant.

5. Can the magnitude of acceleration be negative?

Yes, the magnitude of acceleration can be negative if the object is decelerating or moving in the opposite direction of the applied force.
