Comment WebAssign Problem 1: Consult Interactive Solution 7. In the WebAssign versions of these problems, various details have been changed, so that the answers will come out differently.

The method to find the solution is the same, but you will need to repeat part of the calculation to find out what your answer should have been. A stream of water strikes a stationary turbine blade horizontally, as Fins1613 tutorial solutions week 2 drawing illustrates.

The mass of water per second that strikes the blade is Find the magnitude of the average force exerted on the water by the blade. The incoming water has a momentum mv0 and that of the outgoing water is mvf. A kg swimmer is standing on a stationary kg. Find the recoil velocity that the raft would have if there were no friction and resistance due to the water.

The swimmer and raft constitute an isolated system, so the principle of conservation of linear momentum applies. We will use this principle to find the recoil velocity of the raft.

The lead female character in the movie Diamonds Are Forever is standing at the edge of an offshore oil rig. As she fires a gun, she is driven back over the edge and into the sea.

Suppose the mass of a bullet is 0. Her mass including the gun is 51 kg. REASONING For the system consisting of the female character, the gun and the bullet, the sum of the external forces is zero, because the weight of each object is balanced by a corresponding upward normal force, and we are ignoring friction.

The female character, the gun and the bullet, then, constitute an isolated system, and the principle of conservation of linear momentum applies.

The total momentum of the system before the gun is fired is zero, since all parts of the system are at rest. Momentum conservation requires that the total momentum remains zero after the gun has been fired.

Repeating the calculation for the situation in which the woman shoots a blank cartridge, we have m v — 5. The total momentum of the system remains zero, because momentum is a vector quantity, and the momenta of the bullet and the woman have equal magnitudes, but opposite directions.

Multiple-Concept Example 7 presents a model for solving problems such as this one. Assume that the transmission of the van is in neutral, the brakes are not being applied, and the collision is elastic.

What is the final velocity of a the car and b the van? The final velocities of the car and van are given in terms of the initial velocity of the car by Equations 7.

The final velocity vf1 of the car is given by Equation 7. The final velocity of the van is given by Equation 7. Consult Multiple-Concept Example 8 for background pertinent to this problem. The block has a mass of g. During the collision between the bullet and the wooden block, linear momentum is conserved, since no net external force acts on the bullet and the block.

The weight of each is balanced by the tension in the suspension wire, and the forces that the bullet and block exert on each other are internal forces. During this phase, the tension in the wire a nonconservative force does no work, since it acts perpendicular to the motion. Thus, the work done by nonconservative forces is zero, and the total mechanical energy of the system is conserved.

An application of this conservation law will enable us to determine the height hf. The principle of conservation of linear momentum states that the total momentum after the collision is equal to that before the collision.

Just after the collision, the total mechanical energy of the system is all kinetic energy, since we take the zero-level for the gravitational potential energy to be at the initial height of the block. At the highest point, the total mechanical energy is all gravitational potential energy.Ch a What will your monthly payments be?
