Two fishing boats depart a harbor at the same time, one traveling east, the other south. the eastbound boat travels at a speed 3 mi/h faster than the southbound boat. after 3 h the boats are 45 mi apart. find the speed of the southbound boat.
Answers: 1
the speed of the southbound boat, and 
the speed of the eastbound boat, which is 3 mph faster than the southbound boat. We can write the law of motion for the two boats:
, the two boats are 
apart. Using the laws of motion written at step 1, we can write the distance the two boats covered:
and 
are the two sides. Therefore, we can use Pythagorean theorem and write:
, which is the speed of the southbound boat.

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.)
