Chapter 2, Problem 37R

To determine

To Choose: The correct option.

Answer to Problem 37R

Option (B) is the correct answer.

Explanation of Solution

Formula used:

The equation of motion is,

  $v=u+at$ ........ (1)

Here, $v,u$ , $t$ and $a$ are final velocity, initial velocity, time and acceleration.

Calculation:

Rearranging the equation (1),

  $a=\frac{v-u}{t}$ ........ (2)

From the above equation, it is evident that the initial velocity, final velocity and time are parameter needed for the calculation of acceleration.

Average velocity is not used in the calculation of acceleration.

Conclusion:

Hence, the average velocity is not used in calculating acceleration.
