Use the following information to answer parts a and b. A motorboat is travelling at its maximum speed of 6.0 m s⁻¹ straight across a river, which has a current of 3.8 m s⁻¹ downstream, as shown in the diagram The banks of the river are parallel to each other and straight. a) Calculate the velocity of the boat as seen by someone at the position marked ‘A’ on the diagram. b) If the river is 1100m wide, how long does it take for the boat to reach the other bank?
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.
