Beginning at $t=0$ with initial velocity $4 \mathrm{m} / \mathrm{s},$ a particle moves in a straight line with acceleration $a(t)=3 t^{1 / 2} \mathrm{m} / \mathrm{s}^{2} .$ Find the distance traveled after 25 seconds.

Key Concepts

Integration in Kinematics

Integration is a fundamental tool in calculus used to determine cumulative quantities such as velocity and displacement from acceleration. In kinematics, the process involves integrating an acceleration function to obtain velocity, and further integrating the velocity function to determine the position. Initial conditions are used in these integrations to account for the specific starting values of velocity and position, ensuring an accurate description of the motion.

Position and Displacement

Position denotes the location of an object at a given time, and displacement is the change in position from a starting point. The displacement or distance traveled by an object can be found by integrating the velocity function over time. When the velocity does not change sign (as with constant or always positive acceleration), the magnitude of displacement corresponds directly to the distance traveled.

Velocity

Velocity represents the rate of change of the position of an object. It is obtained by integrating the acceleration function with respect to time, and its value at any specific time includes both the cumulative effect of acceleration and the initial velocity. Understanding velocity is critical in determining how the object's position evolves over time under varying acceleration.

Acceleration

Acceleration is the rate at which an object's velocity changes over time. In physics, it is expressed as the derivative of velocity with respect to time. When acceleration is given as a function of time, it provides the instantaneous changes in speed and direction, serving as the starting point for deriving both the velocity and position of the moving object through integration.
