... 31. (a) The upper limit for centripetal acceleration (same as the radial acceleration – see Eq. 10-23) places an upper limit of the rate of spin (the angular velocity ) by considering a point at the rim (r = 0.25 m). Thus, max = a/r = 40 rad/s. Now we apply Eq. 10-15 to first half of the motion (w ...

momentum
... If you wish to increase the momentum of something as much as possible, you not only apply the greatest force you can, you also extend the time of application as much as possible. Long-range cannons have long barrels. The longer the barrel, the greater the velocity of the emerging cannonball or shell ...

Only external forces can change a system’s momentum. With or without the plate, the exhaust gases exert an ...

The Law of Momentum Conservation
... In most collisions between two objects, one object slows down and loses momentum while the other object speeds up and gains momentum. If object 1 loses 75 units of momentum, then object 2 gains 75 units of momentum. Yet, the total momentum of the two objects (object 1 plus object 2) is the same befo ...
