You are rushing to the train station to catch your morning commute. the train leaves the train station from rest with an acceleration of 0.6 m/s^2. you arrive at the station exactly 4.0 seconds after the train leaves and you immediately start running after the train with a constant velocity of 8.5 m/s.
a. how long after the train leaves the station do you catch up with the train?
b. how far from the train station do you catch up with the train?
c. with what minimum speed would you have to run in order to catch up with the train?

22. the effect of threshold braking is to a cause skids. b. lock wheels. c. prevent locking of wheels. d. increase stopping distance.

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)
