    motion and torque

    Copper
      Problem 1
      a person stands on a platform 10 meters high, and throws an object at 14 m/s at 45 degrees.
      1. how high did the object go?
      2. how long did it travel in the air?
      3. how far did it travel?

      Problem 2
      disk A has a moment of inertia of 6
      disk B has moment of inertia of 1.5
      angular velocity of disk A is 1.0

      1. find the angular velocity of both disk together
      2. find kinetic energy of A and B separately
      3. what difference cause changes in kinetic energy and angular velocity

          We're not going to do your homework for you. You need to make an attempt, here.
