Explanation Write the expression to calculate the average acceleration. a = V − v t Here, a is the average acceleration, V is the final speed, v is the initial speed and t is the time taken. In this case the initial speed is negative since the direction from the wall is taken as positive. Substitute 22.0 m / s for V , − 25.0 m / s for v and 3.50 ms for t in the above equation to calculate a . a = 22.0 m / s − ( − 25

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, fo…

Four capacitors are connected as shown in the figure below. (Let C = 12.0 µF.) A circuit consists of four capacitors. It begins at point a before the wire splits in two directions. On the upper split, there is a capacitor C followed by a 3.00 µF capacitor. On the lower split, there is a 6.00 µF capacitor. The two splits reconnect and are followed by a 20.0 µF capacitor, which is then followed by point b.
