Ahard rubber ball, released at chest height, falls to the pavement and bounces back to nearly the same height. when it is in contact with the pavement, the lower side of the ball is temporarily flattened. suppose the maximum depth of the dent is on the order of 1 cm. find the order of magnitude of the maximum acceleration of the ball while it is in contact with the pavement. state your assumptions, the quantities you estimate, and the values you estimate for them. explain!

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.
