The initial upward speed of the ball in the phenomenon described above is 10 m/s, and the ball is released at a height of 1.5 m above the floor. New Question: In Activity 15b (phenomenon describe above) we assumed that y = 0 at the level of the floor. If, instead, we assume that y = 0 where Christine releases the ball – still 1.5 meters above the floor – will this change the maximum height above the floor attained by the ball? Use the Energy-Interaction Model

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.

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
