    Critical speed of a banked curve (with friction.)

    A concrete highway curve of radius 80.0 m is banked at a 14.0\circ angle. What is the maximum speed with which a 1300 kg rubber-tired car can take this curve without sliding? (Take the static coefficient of friction of rubber on concrete to be 1.0.) I was trying v_max = \sqrt{}\mu_srg but that...

    Tangential Acceleration Along an Oddly Shaped Road

    I have this same problem on my homework, except with 21 m/s. How can you use these formulas if you have no mass or coefficient of friction?

    Tangential Acceleration Problem.

    Guess I should have posted this in homework help section. Apologies, I will from this point on.

    Tangential Acceleration Problem.

    Okay. So I've got three cars that are traveling along a hilly road. One is at the beginning, where its flat, one is at the bottom of the hill, one is at the top. Each is traveling at 21 m/s. I am supposed to find tangential acceleration for each. I tried: a = v^2 / r but that is radial...

    Need help with projectile/friction problem.

    A popular pastime is to see who can push an object closest to the edge of a table without its going off. You push the 100 g object and release it 3.00 m from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.30 m to the floor, and...
