Which of the following statements is not correct regarding the motion of a particle in a straight line?
A particle moving along a straight line has a velocity v m s^{−1}, when it cleared a distance of x m. These two are connected by the relation When its velocity is 1 m s^{−1}, its acceleration is
A particle moves rectilinearly. its displacement x at time t is given by x^{2} = t^{2} + 1. Its acceleration at time t is proportional to
A car starts from rest, attains a velocity of 36 km h^{−1} with an acceleration of 0.2 m s^{−2}, travels 9 km with this uniform velocity and then comes to halt with a uniform deceleration of 0.1 m s^{−2}. The total time of travel of the car is
A particle moving with uniform acceleration has average velocities v_{1}, v_{2} and v_{3} over the successive intervals of time t_{1}, t_{2} and t_{3} respectively. The value of will be
A particle starts from point A moves along a straight line path with an acceleration given by a = p − qx, where p,q are constants and x is distance from point A. The particle stops at point B. The maximum velocity of the particle is
