I'm given a potential diagram for a 440g that is released from rest at a
what are the speeds a b c and d U= 5 @ a U=2 @ b U= 3 @c U= 0 @ d can you help asked 10/04/2010 10:10 |
The diagram is not really necessary.
Ozo's answer gives you the basic idea of which the question is an illustration. What is the initial KE? What is the initial PE? What is the total? What is the PE at b (given) therefore what is the KE repeat for c and d If you know the KE, what relation do you use to get the velocity |
