Answer #1

. A boat crossing a wide river moves with a speed of 15.0 km/h
relative to the water. The water in the river has a steady speed of
6.00 km/h due east relative to the earth.
a) If the boat heads due north, determine the speed of the boat
relative to an observer standing on the shore.
b) What is the angle made between the velocity of the boat relative
to the observer and the north direction?
c) At what...

Two boats are heading away from shore. Boat 1 heads due north at
a speed of 2.98 m/s relative to the shore. Relative to Boat 1, Boat
2 is moving 29.0° north of east at a speed of 1.51 m/s. A passenger
on Boat 2 walks due east across the deck at a speed of 1.17 m/s
relative to Boat 2. What is the speed of the passenger relative to
the shore?

A 290-m-wide river flows due east at a uniform speed of 1.3m/s.
A boat with a speed of 8.9m/s relative to the water leaves the
south bank pointed in a direction 34o west of north. What is the
(a) magnitude and (b) direction of the boat's velocity relative to
the ground? Give the direction as the angle of the velocity from
due north, positive if to the east and negative if to the west. (c)
How long does it take...

A 362-kg boat is sailing 17.0° north of east at a speed of 1.60
m/s. 40.0 s later, it is sailing 40.0° north of east at a speed of
4.40 m/s. During this time, three forces act on the boat: a 30.5-N
force directed 17.0° north of east (due to an auxiliary engine), a
23.8-N force directed 17.0° south of west (resistance due to the
water), and (due to the wind). Find the (a) the magnitude and (b)
direction of...

A section of a river is 252m wide and the water flows east with
a uniform velocity of 1.10m/s. A boat starts at point A on the
south bank and crosses the river to point B on the opposite side.
If the trip takes 3.00min, find the velocity (magnitude and
direction) of the boat with respect to
a. a stationary observer on the ground.
b. a duck floating and moving with the water.

A 379-kg boat is sailing 11.0° north of east at a speed of 1.80
m/s. 35.0 s later, it is sailing 38.0° north of east at a speed of
4.30 m/s. During this time, three forces act on the boat: a 32.1-N
force directed 11.0° north of east (due to an auxiliary engine), a
21.8-N force directed 11.0° south of west (resistance due to the
water), and (due to the wind). Find the (a) the magnitude and (b)
direction of...

A 373-kg boat is sailing 12.0° north of east at a speed of 2.00
m/s. 31.0 s later, it is sailing 39.0° north of east at a speed of
4.00 m/s. During this time, three forces act on the boat: a 31.9-N
force directed 12.0° north of east (due to an auxiliary engine), a
20.8-N force directed 12.0° south of west (resistance due to the
water), and (due to the wind). Find the (a) the magnitude and (b)
direction of...

An airplane heads due west at a speed 150 km/h relative to the
wind. If the wind is moving
at 30 km/h toward the north, what is the speed of the airplane
relative to the ground?
A jet airliner moving initially at 300 mi/h due east enters a
region where the wind is blowing at
100 mi/h in a direction 30◦ north of east. What is the speed of
the aircraft relative to the ground?
A certain river is 0.5...

A swimmer heading directly across a river that is 200 m wide
reaches the opposite bank in 6 min 40 s. During this swim, she is
swept downstream 480 m. How fast can she swim in still water?what
is the speed of the boat relative to an observer standing on the
shore as it crosses the river?What is the speed of the current?

An 79-kg jogger is heading due east at a speed of 3.0
m/s. A 72-kg jogger is heading 51 ° north of east at a speed of 3.4
m/s. Find (a) the magnitude and (b) the direction of the sum of the
momenta of the two joggers. Describe the direction as an angle with
respect to due east.
