A car is travelling straight at 17.7 m/s. After 12 s its speed is 14.1 m/s. Find the car's average acceleration. V = U + at 17.7 = 14.1 + a*12 V-U= at V-U/t 17.7 m/s -14.1 m/s=a*12s 3/12s=a=0.3 m/s^2 If this is correct, if the problem said the plane is going in a northernly direction, if the acceleration is negative, would that be that the plane is heading in a south direction? Please explain the dynamics of this
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.
A car is travelling straight at 17.7 m/s. After 12 s its speed is 14.1 m/s. Find the car's average acceleration.
V = U + at
17.7 = 14.1 + a*12
V-U= at
V-U/t
17.7 m/s -14.1 m/s=a*12s
3/12s=a=0.3 m/s^2
If this is correct, if the problem said the plane is going in a northernly direction, if the acceleration is negative, would that be that the plane is heading in a south direction? Please explain the dynamics of this
