Question

Find the average velocity for the time period beginning when t=2 and lasting:

a) t=2
b) t=0
c) t=4
d) t=2 to t=4

Answer 1

The average velocity for the time period beginning when t=2 is not calculable based on the given information. Thus the correct option is A.

Step-by-step explanation:

The average velocity (V_avg) is calculated as the change in displacement (Δd) divided by the change in time (Δt). Without specific information about the displacement during the time interval starting at t=2, it is not possible to determine the average velocity accurately.

To elaborate, the formula for average velocity is given by:

`\[ V_{\text{avg}} = (\Delta d)/(\Delta t) \]`

Without knowing the displacement
`(\(\Delta d\))`during the time period starting at t=2, it is not feasible to compute the average velocity. The average velocity depends on the change in distance covered during the specified time interval.

In conclusion, the calculation of average velocity requires both the starting and ending positions or the displacement during the given time period. As the displacement information is not provided, the average velocity for the time period beginning when t=2 is indeterminable based on the available data.
