Give your answer in si units and to three significant figures. a train departs station a to travel to station b which is 1188 meters away. the train begins at rest and accelerates at a rate of 2.41 m/s^2 until it reaches a speed of 20.0 m/s. as the train approaches station b, it begins to decelerate at a rate of 1.65 m/s^2 so that it comes to a complete stop just as it arrives at station b. determine the average velocity of the train over the entire trip.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
