Homework Statement In the figure, a string is used to pull a disk of radius 18 cm and mass 9.3 kg. If the incline is 37° and the tension in the string is 20 Newtons find the acceleration of the disk and the force of friction on it. Homework Equations T=I(alpha) The Attempt at a...

It is. It's 1/4 the weight per tire but there's two skid marks so there's two tires so it's 1/2 the weight of the car. I'm just not sure we can assume that we use half the weight instead of all the weight.

dude i think I'm in your class, that is if you go to USI. this is what i got not sure if it's right though. Fr = μN N = the normal force Since only two tires were involved in the skid, the normal force is not going to equal the entire weight of the car, assuming the car is perfectly...

Your cat "Ms." (mass 7.00 kg) is trying to make it to the top of a frictionless ramp 2.00 m long and inclined upward at 30.0 degrees above the horizontal. Since the poor cat can't get any traction on the ramp, you push her up the entire length of the ramp by exerting a constant 100 N force...
