1. The problem statement, all variables and given/known data assume you are taking a trip on a train. you carry a filled suitcase that weighs 170N, and during the course of your trip you are told that the train is moving at 140 km/hr. (a) what do you observe the kinetic energy of the suitcase to be, before you are told the velocity? (b) what do you interpret the kinetic energy of the suitcase to be after knowing the velocity? 2. Relevant equations part B would be utilizing the equation ke= 1/2mv^2 3. The attempt at a solution kE= 1/2(170/9.18)(140)^2 KE= 169834 Im not sure about how to go about part a of the question, how would you determine the kinetic energy if no velocity is given? any information would be highly appreciated thank you.
