Linear Momentum and Collisions
... We were able to solve problems involving these situations by identifying a system and applying a conservation principle, conservation of energy. Let us consider another situation and see if we can solve it with the models we have developed so far: A 60-kg archer stands at rest on frictionless ice an ...

... a) What is the KE at the start of the trial, v = 0 mph? Ans. Ko = 0 J b) What is the KE at the end of the quarter mile? Ans. Kf = ½ mv2 = 2.07x106 J c) How much work is performed on the Corvette during this trial? Ans. Wnet = K = Kf - Ko = 2.07x106 J d) What is the average net power in (W or J/s) g ...

Chapter 9 Linear Momentum and Collisions
... this is a very simple problem to solve if we introduce a new quantity that describes motion, linear momentum. Let us apply the General Problem-Solving Strategy and conceptualize an isolated system of two particles (Fig. 9.1) with masses m 1 and m 2 and moving with velocities v1 and v2 at an instant ...

Conservation of Energy and Momentum
... When you drop a ball, does its speed increase because the gravitational force is doing work on it, or because its gravitational potential energy is decreasing? Well, both (or more precisely, either). Work and potential energy are two different ways of talking about the same thing (at least for conse ...
