    hell all plz help me life or death situation

    the starship enterprise wishes to fly to a distant galaxy 85 light years away. at what speed would it have to travel in order that the distance to the galaxy would only be 20 light years? :rolleyes:

    a movving particle has a rent mass which is double in its kinetic energy. Find its speed and momentum :!!)

    you are sitting at rest on your brrom stick one day when a witch flies by at 0.25c the witch says her boomstick is 1.3 m long and yours is 1.5 m long what so you dtermine the length of these two brromsticks to be? :surprised

    A set of homework problems really isn't a life or death situation. But welcome to physics forum. If you read the FAQ's here, you'll see that there is a forum set aside for homework problems, and that showing your attempts to solve the problems is highly encouraged.
