Question

A particle moves with uniform acceleration along a straight line. The average velocity over an interval is equal to the instantaneous velocity at:

• A. The beginning of the interval
• B. The end of the interval
• C. The midpoint of the interval
• D. Any point in the interval

Hint:

For uniform acceleration, average velocity equals velocity at mid-time.

Answer 1

The Correct Option is C

For uniform acceleration, \[ v_{\text{avg}}=\frac{u+v}{2} \] This equals the instantaneous velocity at the midpoint of the time interval.
