A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.
2 Rutherford +2e +79e Rutherford discovered the nucleus of atoms by firing a particles at gold foil. An a particle has a charge of q = +2e and a mass of m = 6.64 x 10-27 kg. A gold nucleus has charge of Q = +79e. You may ignore the motion of the gold nucleus in this problem. Suppose an a particles is traveling directly toward a gold nucleus. If the speed of the a particle is v = 1.9 x 10' m/s when it is 1.0 m from the gold nucleus, how close to the gold nucleus will the a particle come before it stops and reverses direction?
0.5m away 3. You (who have a mass of 72 kg) are floating out in space holding an 11 kg ball. It also just so happens that your body carried an electric charge of 60 μC and the ball holds a charge of -310 mc. Suppose you throw the ball away from you at a speed of 13 m/s. How far away from you does the ball get before coming back? (If you determine that the ball will never come back, determine the speed with which it will forever drift away from you.). It is worth mentioning that you will also move backwards when you throw the ball forwards. Don't forget this.
