A treasure map directs you to start at palm tree
and walk due north for 15.0 m. You are then to turn
90° and walk 22.0 m; then turn 90° again and
walk 5.00 m.
Give the distance from the palm tree,and the direction to north, for each of the four possible locations of the treasure .
The direction of the 90° turns are the possible directions used for the calculations
The four distances and directions are;
24.2 m, 65.6° West of North29.7 m, 42.7° East of North24.2 m, 65.6° East of North29.7m, 47.7° West of NorthReason:
Let point A represent the motion of the treasure hunter, we have:
Turning West then West;
Walking due north to location (0, 15)
Turn 90° West and walk 22.0 m to the location (-22, 15)
Turn 90° West again and walk 5.00 m. to the location (-22, 10)
The location of point A = (-22, 10)
[tex]Direction \ of \ point \ A = arctan \left(\dfrac{10}{-22} \right) \approx -24.4^{\circ}[/tex]
Direction to North = 90° - 24.4° ≈ 65.6°
Distance = √((-22)² + 10²) ≈ 24.2
Therefore, we have;
24.2 m, 65.6° West of NorthTurning East then West:
Turn 90° East and walk 22.0 m to the location (22, 15)
Turn 90° West again and walk 5.00 m. to the location (22, 20)
The location of point A = (22, 20)
[tex]Direction \ of \ point \ A = arctan \left(\dfrac{20}{22} \right) \approx 42.7^{\circ}[/tex]
Direction to North = 90° - 42.3° ≈ 47.7° East
Distance = √((-22)² + 20²) ≈ 29.7
Therefore, we have;
29.7 m, 42.7° East of NorthTurning East then East:
Turn 90° East and walk 22.0 m to the location (22, 15)
Turn 90° East again and walk 5.00 m. to the location (22, 10)
The location of point A = (22, 10)
[tex]Direction \ of \ point \ A = arctan \left(\dfrac{10}{22} \right) \approx 24.4^{\circ}[/tex]
Direction to North = 90° - 24.4° ≈ 65.6° East
Distance = √((-22)² + 10²) ≈ 24.2
Therefore, we have;
24.2 m, 65.6° East of NorthTurning West then East:
Turn 90° West and walk 22.0 m to the location (-22, 15)

A rubber duck sat is floating on the surface
on the water. 10N of weight is acting
DOWNWARDS on the water. What other
force must be acting to allow the duck to
float?
The other force that must be acting on the duck is upthrust of 10 N.
The given parameters;
weight of the rubber duck, W = 10 NWhen the weight of the object is equal to the upthrust, the apparent weight will be zero and the object will float in the liquid. This is known as principle of floatation.
Since the given weight of the rubber duck is 10 N, then the upthrust on the duck will be 10 N to enable the duck float on the water.
Thus, the other force acting on the duck is upthrust of 10 N.

What is the difference between thrust and applied force?
Answer:
Thrust acts on the accelerated object in the direction opposite to the applied force hence it accelerates the object in the direction opposite to the applied force. ... Its magnitude is equal to that of applied force. It always increases the velocity of the object.
Explanation:
Why is air pressure lower on top of the airplane wing?
Answer:
Explanation:
Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing.

What is the gravitational force acting on a 53 kg object standing on the surface of the Earth?
a) 5.3 N
b) 63N
c)48N
d) 530N
Answer:
D.
Explanation:
DId the test
The gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.
What is Weight ?
Weight is the force exerted by earth on a body on the surface of earth. Mathematically -
W = mg
Given is a 53 kg object standing on the surface of the Earth.
The gravitational force acting on the body will be same as it weight and will be directed towards the center of earth. Using the formula for weight -
W = mg = 53 x 10 = 530 N [taken g = 10 m/s²]
Therefore, the gravitational force acting on the body of mass 53 Kg on earth will be 530 Newtons.
