Suppose that this boat was aimed directly up stream. What will be the final kinetic energy of this wheel at the end of the 5. Was the collision between these two masses elastic or inelastic? Develop an expression which will predict the charge contained within a Gaussian surface which has a radius r that is greater that the radius R of the solid cylinder. What will be the acceleration of the cart as it moves down the incline? One of the classic stories of science fiction is the concept of a spoked wheel space station [as in A Space Odyssey]. What is the spring constant of this spring? Suppose that the ball escaped from the roulette wheel while in the position shown, what will be the direction of motion of the ball as it exits the wheel?
