Question

For a moving body at any instant of time
1) If the body is not moving, the accelaration is neccesarily zeo
2) If the body is slowing, the retardation is negative
3) If the body is slowing, the distance is negative
4) If the displacement, velocity and acceleration at the instant are known, we can find the displacement at any given time in future.

please help me with the appropriate option​

Answer 1

Question

For a moving body at any instant of time:

A) if the body is not moving, the acceleration is necessarily zero.  

B) if the body is slowing, the retardation is negative.  

C) if the body is slowing. the distance is negative.

D) if displacement, velocity and acceleration at that instant are known, we can find the  displacement at any give  n time in future.

Answer

D) if displacement, velocity and acceleration at that instant are known, we can find the  displacement at any given time in future.
