Solve problems involving acceleration

Acceleration

9.2

Acceleration

	Definition

	Acceleration is the rate of change of speed with time, in a linear motion Deceleration is the opposite of acceleration, where the speed reduction occurs

Formula

\(\text{Acceleration} = \dfrac{\text{Speed}}{\text{time}}\)

	Example

	A car takes \(8\text{ seconds}\) to its velocity from \(10\text{ m/s}\) to \(30\text{ m/s}\). What is its acceleration?

	Answers: \(\begin{aligned}\text{Acceleration} &= \dfrac{(30-10)\text{ m/s}}{8\text{ s}} \\\\&=2.5\text{ m/s}^2. \end{aligned}\)
