which of the following best represents the velocity of the water? 1. < 0, -4.0 > m/s 2. < 4.0, 0 > m/s 3. < 0, 4.0 > m/s 4. < -4.0, 0 > m/s Question B: Which of the following best represents the desired velocity of the boat?
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
Please refer to the question that is attached.
The boat in the picture below is tring to travel north to cross the river at 10 m/s, however the water in the river is flowing west at 4.0 m/s. The boat instead angles itself to counteract the flow of the river. For this problem orient the coordinate axes with x pointing east and y pointing north.
Question A: which of the following best represents the velocity of the water?
1. < 0, -4.0 > m/s
2. < 4.0, 0 > m/s
3. < 0, 4.0 > m/s
4. < -4.0, 0 > m/s
Question B: Which of the following best represents the desired velocity of the boat?
1. < 0, 10.0 > m/s
2. < -10.0, 0 > m/s
3. < 10.0, 0 > m/s
4. < 0, -10.0 > m/s
Question C: Which of the follwing best represents the adjusted velocity of the boat?
1. < -10.0, -4 > m/s
2. < 4, 10.0 > m/s
3. < 10.0, 4 > m/s
4. < -4, 10.0 > m/s
Question D: Which is the heading of the boat? In other words, what is the angle θ that the boat makes with north? Answer this question in degrees.
Question E: If the far shore is 100 m away, how long will it take the boat to travel from one shore to the other? Answer in seconds.
