Unformatted text preview: Concept Check – Cart on Track Consider a cart on a horizontal frictionless table. Once the cart has been given a push and released, what will happen to the cart? 1. slowly come to a stop 2. continue with constant acceleration 3. continue with decreasing acceleration 4. continue with constant velocity 5. immediately come to a stop Concept Check – Cart on Track Consider a cart on a horizontal frictionless table. Once the cart has been given a push and released, what will happen to the cart? 1. slowly come to a stop 2. continue with constant acceleration 3. continue with decreasing acceleration 4. continue with constant velocity 5. immediately come to a stop After the cart is released, there is no longer a force in the x-direction. This does not mean that the cart stops moving. It simply means that the cart will continue moving with the same velocity it had at the moment of release. The initial push got the cart moving, but that force is not needed to keep the cart in motion. Concept Check – Cart on Track (2) We just decided that the cart continues with constant velocity. What would have to be done in order to have the cart continue with constant acceleration? 1. push the cart harder before release 2. push the cart longer before release 3. push the cart continuously 4. change the mass of the cart 5. it is impossible to do that Concept Check – Cart on Track (2)...
