Jason takes off across level water on his jet-powered skis. The combined mass of Jason and skis is 75 kg (the mass of the fuel is negligible). The skis have a thrust of 200 N and a coefficient of kinetic friction on water of 0.1.
Unfortunately, the skis run out of fuel after only 90 s. What is Jason's top speed? A) 150 m/s
B) 240 m/s
C) 24 m/s
D) 90 m/s
Question 2
Two identical loudspeakers that are 5.00 m apart and face toward each other are driven in phase by the same oscillator at a frequency of 875 Hz. The speed of sound in the room is 344 m/s.
If you start out standing midway between the speakers, find the shortest distance you can walk toward either speaker in order to hear a minimum of sound.
A) 0.197 m B) 0.295 m C) 0.0983 m D) 0.393 m E) 0.590 m
