Use the graph below to answer the following question: if average acceleration is calculated using the equation, “ change in velocity / change in time,” what is an abject acceleration at 4s? be sure to include units in your math work and in your final answer.

Explanation:

Average Acceleration

Acceleration is a physical magnitude defined as the change of velocity over time. When we have experimental data, we can compute it by calculating the slope of the line in velocity vs time graph.

Note: We cannot see if the time axis is numbered in increments of 1 second, and we'll assume that.

When , the graph shows a value of

When , the object is at rest,

We compute the average acceleration as

from

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
