Question

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 the force . Express the direction as an angle with respect to due east.

Answer #1

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 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 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 ship sailing in the Gulf Stream is heading 26.0° west of north
at a speed of 4.05 m/s relative to the water. Its velocity relative
to the Earth is 4.75 m/s 5.40° west of north. What is the velocity
of the Gulf Stream? (The velocity obtained is typical for the Gulf
Stream a few hundred kilometers off the east coast of the United
States. Enter the magnitude in m/s and the direction in degrees
north of east.)
magnitude ?m/s...

Answer the following question"
1A: The boat in the figure is heading due north as it crosses a
wide river with a velocity of 11.5 km/h relative to the water. The
river has a uniform velocity of 4.90 km/h due east. Determine the
velocity of the boat with respect to an observer on the riverbank.
find the
magnitude
direction
1B: Suppose the river is flowing east at 2.60 m/s and the boat
is traveling south at 4.40 m/s with respect...

A passenger on a moving train walks at a speed of 1.50 m/s due
north relative to the train. The passenger's speed with respect to
the ground is 4.5 m/s at an angle of 31.0°west of north. What are
the magnitude and direction of the velocity of the train relative
to the ground?

You have a small boat which travels through water at a speed of
6.0 m/s. You take it out on a section of a local river where the
water flows from north to south at a speed of 4.0 m/s.
(a) First, you head south (i.e. downstream) in your boat. Draw a
vector which represents the velocity of the boat relative to the
water, and a vector that represents the velocity of the water
relative to the shore. Then add...

A proton, traveling with a velocity of 4.9 × 106 m/s
due east, experiences a maximum magnetic force of 8.0 ×
10-14 N. The direction of the force is straight down,
toward the surface of the earth. What is the magnitude and
direction of the magnetic field B, assumed perpendicular
to the motion?
B = Number ___
B) Units ____ ( W,J,No units,V,m,C,T. A, V/m) options
C)____
East, South, West or North
the tolerance is +/-2%

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.

A jet is flying due north relative to the ground. The speed of
the jet relative to the ground is 155 m/s. The wind at the jet’s
altitude is 40.0 m/s toward the northeast (45.0∘∘ north of east).
Suppose that the +x-axis is directed eastward and the +y-axis is
directed northward. Find the speed of the jet relative to the air
(its airspeed). Find the direction in which the pilot of the jet
must point the plane so that it...
