A car travels in a straight line with varying velocity given by $\mathrm{v}=\left|\mathrm{t}-\mathrm{t}_{0}\right| \mathrm{m} \mathrm{s}^{-1}$ for $0 \leq \mathrm{t} \leq 2 \mathrm{t}_{0}$ where, $\mathrm{t}=$ time and $\mathrm{t}_{0}=$ time at which velocity is zero. The distance travelled by the car in this interval is (a) $\mathrm{t}_{0}^{2}$ (b) $2 \mathrm{t}_{0}^{2}$ (c) $\frac{3}{2} t_{0}^{2}$ (d) 0

Key Concepts

Kinematics and Velocity-Displacement Relationship

In kinematics, the relationship between velocity and displacement is established through integration. The displacement of an object can be determined by integrating its velocity over a given time period, which may involve breaking the integration into segments if the velocity function behaves differently in different intervals.

Definite Integration

Definite integration is a fundamental calculus tool used to calculate accumulated quantities like displacement when the velocity function is known. It involves computing the area under the curve of a velocity function over a specified interval in time, taking into account the specific behavior of the function over that interval.

Piecewise Functions

Piecewise functions are functions defined by different expressions over various intervals. They are crucial when a behavior of a quantity, such as velocity, is described differently depending on time or other variables, as seen in many kinematics problems where motion changes behavior at specific instants.

Absolute Value Function

The absolute value function describes the magnitude of a real number regardless of its sign, leading to a natural piecewise definition. In the context of motion, it is often used to ensure that quantities like velocity are treated correctly when direction changes, necessitating handling of different cases for analysis.
