w your car using a 0.16 kg sponge. You apply a force downward and across the flat hood of the car. The force is modeled force acting 36 deres below the
rotal. This force is enough to push the sponge across the surface with a constant velocity, so that kinetic friction is acting and the acceleration is the concert
etc friction between sponge and car is 0.1, calculate the force in that will give the sponge a constant speed. (Use g - 10 m/s)

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.

Drag each item into the proper state of matter category.

Does work output exceed work input when a machine is used? a) yes, it does, as machines create energy. b) it depends on the type of machine used. c) no, it doesn’t, as machines are inefficient. d) no, it doesn’t, as machines cannot create energy.
