Two boat landings are 4.1 km apart on the same bank of a stream that flows at 6.5 km/hr. A motorboat makes the round trip between the two landings in 2.3 hr.
What is the speed of the boat relative to the water?
Answer in units of km/hr.
Solutions
Expert Solution
Here ,
let the speed of boat relative to water is v
speed of stream , u = 6.5 km/hr
Now,
4.1/(6.5 + v) + 4.1/(v - 6.5) = 2.3
solving for v
v = 8.52 km/hr
the speed of the boat relative to water is 8.52 km/hr

Two point source three meter apart are driven by the same
oscillator at a frequency of 800 hz. The sources emit energy in the
form of spherical waves. An observer initially hears a maximum at a
distance 10 m along the perpendicular bisector of the line joining
the two sources. What distance (in m) must observer move along a
line parallel to the line joining the two sources before reaching a
minimum intensity? (Assume the speed of sound is 343...
