A particle moves along a straight line. A force acts on the particle along velocity which produces a constant power. It stars with initial velocity `3m//s` and after mofing a distance `252m`, its velocity is `6m//s`. Find the time taken (in sec).

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 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 straight line in same direction for 20 seconds with velocity 3 m//s and the moves with velocity 4 m//s for another 20 sec and finally moves with velocity 5 m//s for next 20 seconds. What is the average velocity of the particle?

A car is moving with the initial velocity 15 m/s. Car stoped after 5s by application of breaks. Find the retardation (Decelaration).

A particle is moving along a straight line along x-zxis with an initial velocity of 4 m//s towards positive x-axis. A constant acceleration of 1 m//s^(2) towards negative x-axis starts acting on particle at t=0 . Find velocity (in m//s ) of particle at t=2 s .
