Oh wow, yea that's just what kind of day I was having yesterday. :frown: Sorry for being so difficult and thanks for sticking around for me.
Alright so about this friction force. Would we eliminate it by saying the friction force is equal to the mass times acceleration of the car? If so and...
Alrighty I think I might have it now!
The engine supplies a torque to the tires, which in turn gives them an angular acceleration.
τ=Iα
α=a/r
so, a= τr/I
This makes much more sense. I have no idea what I was thinking earlier. I'm pretty sure this is correct this time, :smile: and...
:) thanks
I get that friction is the only external force here. I guess I'm just having trouble understanding how to get the acceleration for the car using the moment of inertia.
I start off by saying the Fr=Iα, which is the torque created by the tires that will move the car. Then i need to...
Homework Statement
I have a car with a mass (m) and tires having moment of inertia (I). I need to find an equation for the acceleration of the car from what is given. thanks in advance for the help.
