Question

question 1 (1 point)
which of the following is the best approximation of the instantaneous velocity of a moving object at t=5?
○ the average from t=5 to 5.5
○ the average from t=5 to 5.1
○ the average from t=5 to 5.7
○ the average from t=5 to 5.9
○ the average from t=5 to 5.3

Explanation:

Instantaneous velocity at a point is the limit of average velocity as the time interval approaches 0. A smaller interval around t=5 gives a better approximation. Among the options, the interval from t=5 to 5.1 has the smallest width (0.1), so it is the closest approximation to the instantaneous velocity at t=5.

Answer:

the average from t=5 to 5.1
