Q1. 3/204 from the book, slightly extended/modified. Freight car A of mass ma is rolling to the right with speed vo when it collides with freight car B of mass mg initially at rest. The two cars are coupled together at impact, so that they move together with a common velocity ("plastic collision"). Answer all the questions below in terms of quantities given, namely, v, ma and mB. a) Compute their common velocity immediately after the impact b) Compute the impulse of car A on car B. Note: Impulse on car B = Momentum change of car B. c) Compute the loss in total kinetic energy of the system (A+B) due to the collision. A

Check Your Understanding Notice that the mass of the air in the tank was neglected in the analysis and solution. How would the solution method changed if the air was included? How large difference do you think if would make in the final answer?
What is the momentum (as a function of time) of a 5.0-kg particle moving with a velocity v →(t) = (2.0i ^ + 4.0tj ^) m/s ? What is the net force acting on this particle?
An astronaut floating at rest in space has run out of fuel in her jetpack. She realizes that throwing tools from her toolkit in the opposite direction will help propel her back toward the space station. If the astronaut has a mass of 85 kg and she throws a hammer of mass 4.5 kg at a speed of 4 m/s, what will be the approximate resultant velocity that carries her back to the space station?
USING THE UAM FORMULA, SOLVE: A constant force of 3.5 N acts on a 7 kg block, initially at rest, for 7.0 s. Find the(a) acceleration of the block, (b) speed of the block at the end of 7.0 s, (c) change in momentum of the block, and (d) impulse produced by the force.
Two train cars on a frictionless track have a completely inelastic collision in which they "couple" together. The car on the left has mass 16.1 tons and velocity 16.1 m/s to the right; the other train has mass 10.8 tons and velocity 13.1 m/s to the left. After the collision, what is the velocity of the pair fo cars? Your answer should be in tons times m/s, but you don't need to write the units, just the number. "To the right" is taken as positive, so make sure you have the sign right. (If your answer is positive, you don't need to write a "+" sign.)
