Astudent needs to measure the drag on a prototyped of characteristic length da moving at velocity up in air at sea-level conditions. he constructs a model of characteristic length dm, such that the ratio dpl/dm a factor f. he then measures the model drag under dynamically similar conditions, in sea-level air. the student claims that the drag force on the prototype will be identical to that of the model. is this claim correct? explain.

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.)
