Respuesta :

The instantaneous acceleration of the object at time = 6 seconds is 2 m/s²

What is instantaneous acceleration?

This is simply defined as the ratio of change in velocity during a given time interval.

On a velocity-time graph, the instantanous acceleration is equal to the slope.

How to determine the instantaneous acceleration

From the question given, the following data were obtained:

  • Change in time = 6 - 5.5 = 0.5 s
  • Change in velocity = 2 -1 = 1 m/s
  • Instantaneous acceleration =?

Instantaneous acceleration = slope

But,

Slope = Change in velocity / Change in time

Thus,

Instantaneous acceleration = Change in velocity / Change in time

Instantaneous acceleration = 1 / 0.5

Instantaneous acceleration = 2 m/s²

Thus, the instantaneous acceleration at time = 6 s is 2 m/s²
