An object moves with constant acceleration a. Which of the following expressions are also constant?

A

`(d|v|)/(dt)`

B

`|(dv)/(dt)|`

C

`(d(v^2))/(dt)`

D

`(d(v/|v|))/(dt)`

Text Solution

Verified by Experts

The correct Answer is:
B
If a= constant
Then |a| is also constant of `|(dv)/(dt)|`=constant
