Rahim's motorcycle has a maximum speed of 200 km/s is traveling while moving at 80 km/s when he is at Kuantan. If the speed of Rahim's motorcycle is then decreased at a = -(0.06 s) km/s2, where s is the distance in kilometers measured from Kuantan as shown in Figure Q3 (a). (0) (1) (ii) Demonstrate the speed when Rahim's motorcycle reaches Hulu Langat. Demonstrate the acceleration when Rahim's motorcycle reaches Hulu Langat. If Rahim's motorcycle starts from rest at Bangkok and accelerates 0.09 km/s2 for 75 s in straight road. Afterwards it travels with a constant velocity for 20 minutes. It then decelerates at 2 km/s2 until it is brought to rest at Hulu Langat. Calculate the distance between Bangkok and Hulu Langat.
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.
