the picture below shows two cars a and b traveling next to each other in the same
direction. car a is traveling with a constant velocity of va = 10.2 m/s while car b is
traveling with a constant velocity of vb = 30.1 m/s. initially at time ta = os the cars are
separated by 500 meters. at some final timet, in the future, both cars are side-by-side.
500 m
to the nearest tenth of a second, at what final time ty are the cars be side-by-side?

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
