JEE Main & Advanced Physics Motion in a Straight Line / सरल रेखा में गति Question Bank Non-uniform Motion

  • question_answer
    The distance travelled by a particle is proportional to the squares of time, then the particle travels with                              [RPET 1999; RPMT 2000]

    A)             Uniform acceleration

    B)             Uniform velocity

    C)             Increasing acceleration           

    D)             Decreasing velocity

    Correct Answer: A

    Solution :

                    \[s\propto {{t}^{2}}\] (given)\[\therefore \] \[s=K{{t}^{2}}\]             Acceleration \[a=\frac{{{d}^{s}}s}{d{{t}^{2}}}=2k\] (constant)                      It means the particle travels with uniform acceleration.
