Q. No.The displacement \(x\) (in \(\text m\)) of a particle of mass \(m\) (in \(\text{kg}\)) moving in one dimension under the action of a force, is related to time \(t\) (in \(\text s\)) by; \(t = (\sqrt x +3 ).\) The displacement of the particle when its velocity is zero will be:
| 1. | \(4~\text m\) | 2. | zero |
| 3. | \(6~\text m\) | 4. | \(2~\text m\) |

A particle moves along a straight line \(OX.\) At a time \(t\) (in seconds), the displacement \(x\) (in metres) of the particle from \(O\) is given by \(x= 40 +12t-t^3.\) How long would the particle travel before coming to rest?
| 1. | \(24~\text m\) | 2. | \(40~\text m\) |
| 3. | \(56~\text m\) | 4. | \(16~\text m\) |
