If `S_(n)=2+0.4n` find initial velocity and acceleration

If Sn=2+0.4n find initial velocity and acceleration

A particle moves in a straight line as s =alpha(t-4)+beta(t-4)^(2) . Find the initial velocity and acceleration.

If reation between distance and time is s =a + bt + ct ^(2) find initial velocity and acceleration.

An object, starting with an initial speed and moving at constant acceleration traveIs 150 m in 5 s. The acceleration stops after this and in the next 5 s the object traveIs 200 m farther. Find the initial velocity and acceleration of the object.

A body is moving with a uniform acceleration coverss 40 m in the first 4 s and 120 m in next 4s. Its initial velocity and acceleration are

A car travels a distance 100 m with a constant acceleration and average velocity of 20 m s^(-1) . The final velocity acquired by the car is 25 m s^(-1) . Find : (i) the initial velocity and (ii) acceleration of car.

A particle is moving with initial velocity 1m/s and acceleration a=(4t+3)m/s^(2) . Find velocity of particle at t=2sec .

Chek the correctness of the relation, S_(n_(th)) = u +(a)/(2)(2n -1), where u is initial velocity, a is acceleratin and S_(n_(th)) is the distance travelled by the body in nth second.
