Two students grab a slinky and start waving it up and down. a third student counts the number of waves that pass by every second and measures the distance between the wave peaks. this data is recorded and a graph is made to show the results.

determine the velocity of the wave produced.

a) 1 m/s

b) 2 m/s

c) 3 m/s

d) 6 m/s

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.

The slope of a velocity time graph over any interval of time gives the during that interval

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
