An object moves along the $x$ axis according to the equation $x(t)=\left(3.00 t^{2}-2.00 t+3.00\right) \mathrm{m} .$ Determine (a) the average speed between $t=2.00 \mathrm{s}$ and $t=3.00 \mathrm{s},$ (b) the instantancous speed at $t=2.00 \mathrm{s}$ and at $t=3.00 \mathrm{s},$ (c) the average acceleration between $t=2.00 \mathrm{s}$ and $t=3.00 \mathrm{s},$ and $(\mathrm{d})$ the instantaneous acceleration at $t=2.00 \mathrm{s}$ and $t=3.00 \mathrm{s}$.

Key Concepts

Average Speed

Average speed is defined as the total distance traveled divided by the time taken. It provides a measure of the overall rate of motion over a time interval without considering changes in direction or variations in speed during that interval.

Instantaneous Speed

Instantaneous speed is the magnitude of the velocity at a specific moment in time. It is calculated as the derivative of the position function with respect to time and represents the rate of motion at that exact instant.

Average Acceleration

Average acceleration is defined as the change in velocity divided by the time interval over which the change occurs. It gives an overall measure of how the velocity of an object is changing over a finite period.

Instantaneous Acceleration

Instantaneous acceleration is the rate of change of velocity at a particular moment. It is found by differentiating the velocity function with respect to time, or by taking the second derivative of the position function, and reflects the acceleration at that specific time.
