The boat had triangular sails.
The boat was small and had two triangular sails.
Tangent(theta) is sine over cosine, or y over x. x is 120. Theta is 32 and 37. y1 is height of cliff, and y2 is height of cliff plus flagpole.Tan(32) = y1 / 120, so y1 = 120 tan(32) = 75.Tan(37) = y2 / 120, so y2 = 120 tan(37) = 90.Height of flagpole is y2 - y1 = 90 - 75 = 15.All results rounded to nearest integer.
Not intentionally. They use a map book with notes of previous trips and water depth. The map book and notes are a pilot's prized possession and take years to fill out. Many of the pilots on the waterways can draw the whole river they operate with every turn and marker from memory. Its Skill and practice more than trig.
At the start his distance from the lighthouse is 100/tan(60) = 86.6 m. After 2 minutes his distance from the lighthouse is 100/tan(45) = 70.7 m. He travels 15.9 m in 2 minutes = 7.9 m per minute.
propeller
The part of the boat that rotates to power it forward and backward is the propeller. When the propeller spins in one direction, it pushes water backward, propelling the boat forward. Conversely, spinning it in the opposite direction pushes water forward, allowing the boat to move backward. The rotation of the propeller is typically driven by the boat's engine.
The part of the boat that controls the direction of power forward or backward is the propeller. When the engine's power is directed to the propeller, it rotates in one direction to move the boat forward. Reversing the direction of the propeller's rotation propels the boat backward. The throttle and gear shift mechanism manage this process by adjusting the engine's output and changing the rotation direction.
The oars or when a motor is used, the propellers on the shaft sticking in the water.
The part of the boat that rotates it forward and backward is the rudder, which is controlled by the steering mechanism. When the rudder is angled, it creates a force that turns the boat in the desired direction. Additionally, the propeller, driven by the engine, propels the boat forward or backward, allowing for movement in either direction. Together, these components enable precise steering and maneuverability.
propeller
When you row a boat, the oars push backward against the water, creating a reaction force that propels the boat forward, as described by Newton's third law of motion—every action has an equal and opposite reaction. As the oars move backward, they displace water, generating thrust that moves the boat in the opposite direction. This efficient transfer of energy allows the boat to move forward while the oars are pulled back.
The boat goes back word because when you jump your tippy- toes are the only thing left on the boat, and then your feet push forward to do the rest, which makes the boat go backwards.
When a person steps forward from a small boat onto a dock, they exert a force on the boat in the direction of their movement. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. As the person pushes off the boat to move forward, the boat experiences a recoil in the opposite direction, causing it to move backward in the water. This movement is a result of the conservation of momentum in the system.
The most commen example given is stepping out of a row boat. You go forward, the boat goes backward.
because every action has an oppersite reactione.g.man pulls paddle backwardsoppersite reaction, man (in the boat) gets pushedforwards (with boat)
This scenario demonstrates the principle of conservation of momentum. When the person jumps forward, they exert a force on the boat in the opposite direction, causing it to move backward. This interaction illustrates Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
