Q1. A locomotive is pulling a number of identical wagons along a level track and accelerating. Friction is negligible. Starting from the last wagon, the ratio of the forces between adjacent wagons is?
Q2. What is the RMS speed of Helium atoms when the temperature of the Helium gas is 393 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg, Boltzmann's constant is: kB = 1.38×10-23 J/K.)
What is its velocity at impact? What will its average velocity be? What will its average speed be.
What was the power of the motor that kept the wheel rotating at 6.5 rev/hr in spite of friction.
What is momentum of a truck speeding down the highway at a given instant? Discuss how the momentum is changed if the truck loses some of its cargo while maintaining the same velocity.
