Q1. Two identical piano strings of length 0.755 m are each tuned exactly to 440 Hz. the tension in one of the strings is then increased by 1 %. If they are now struck, what is the beat (difference in) frequency between the fundamentals of two strings?

Q2. Assume you are driving on the interstate at 82mph when you see a highway patrol car parked up ahead. You apply your brakes, decelerating at a constant rate of 4mph/sec until you have reduced your speed to 65mph. You then maintain a constant speed of 65.0 mph. You pass the patrol car 16 seconds after you at first applied the brakes and are relieved that he doesn't pull out after you. How far away was the highway patrol car when you first saw it?
