a particle moving along a straight line with uniform acceleration has velocities `7 m//s` at A and `17 m//s` at C. B is the mid point of AC. Then :-

A particle moves in a straight line with a uniform acceleration a. Initial velocity of the particle is zero. Find the average velocity of the particle in first 's' distance.

A particle moves in a straight line with a uniform acceleration a. Initial velocity of the particle is zero. Find the average velocity of the particle in first 's' distance.

A particle moves in a straight line with a uniform acceleration a. Initial velocity of the particle is zero. Find the average velocity of the particle in first 's' distance.

A particle moves with uniform acceleration along a straight line AB . Its velocities at A and B are 2 m//s and 14 m//s respectively. M is the mid-point of AB . The particle takes t_1 seconds to go from A to M and t_2 seconds to go from M to B . Then t_2 : t_1 is.
