HW #8: Chapter 9--Momentum
... The more momentum an object has, the more impulse is needed to stop it. However, this impulse can be provided via a large force acting over a short time interval or a relatively small force acting over a relatively long time interval. If you are driving down the highway at 55 , you can stop your ca ...

... Translation is motion along a straight line but rotation is the motion of wheels, gears, motors, planets, the hands of a clock, the rotor of jet engines and the blades of helicopters. First figure shows a skater gliding across the ice in a straight line with constant speed. Her motion is called tran ...

... Nearly all modern airplanes use jet propulsion to fly. Jet engines and rockets work because of conservation of linear momentum. A rocket engine uses the same principles as a jet, except that in space, there is no oxygen. Most rockets have to carry so much oxygen and fuel that the payload of pe ...

... • Use the right-hand rule to determine the sign of λ . In other words, point the four fingers of your right hand in the direction of n⊥ , and then curl them in the direction of b⊥ . If you thumb points in the direction of λ , the sign of λ is positive, otherwise it is negative. ...

... The barbell system weighs 60 kg. The weight lifter lowers the barbell 0.35 m, at which point it is moving at 0.5 m/s. c) The barbell was at rest but know it is moving at 0.5 m/s so it has gained 7.5 Joules (½mv2 = ½ x 60 x 0.52) of kinetic energy. But it is 0.35m lower in the gravitational field so ...

... The word momentum is often used to describe something moving that will be hard to stop or turn. Does that sound like anything we've studied? How about Newton's 1st Law of Motion? If something is hard to stop or turn, that means it has a lot of inertia, or mass. And if it is moving, that means it has ...
