) A car is accelerating uniformly as it passes two checkpoints that are 30 m apart. The time taken between checkpoints is 4.0 s and the car's speed at the first checkpoint is 5 m/s. Find a) the car's acceleration b) speed at the second checkpoint
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.
1) A car is accelerating uniformly as it passes two checkpoints that are 30 m apart. The time taken between checkpoints is 4.0 s and the car's speed at the first checkpoint is 5 m/s. Find a) the car's acceleration b) speed at the second checkpoint.
2) A plane starts from rest and accelerates along the ground before takeoff. It moves 600 m in 0.20 min. Find a) the acceleration, b) speed at the end of 12 s, c) distance moved during the twelfth second.
