Starting from rest objects 

A particle moves with constant acceleration for 6 seconds after starting from rest. The distance travelled during the first three consecutive 1 seconds interval is in the ratio?

A body moving from rest with uniform acceleration travels a distance 'X' in the first t seconds and travels a distance 'Y' with same acceleration in the next '2t' seconds, then

A body of mass 5 kg having a velocity of 80ms−1 experiences a force in the opposite direction. The body is brought to rest in 8 sec. What is the retardation produced by the force?

For a body performing motion with uniform speed, the distance-time graph is

A car accelerates uniformly from 18km/h to 36km/h in 5s. The distance covered by the car will be

In a motion with constant acceleration the velocity is reduced to zero in 5 seconds and after covering a distance of 100 m. The distance covered by the particle in next 5 second will be :-

A sprinter completes a round on a circular path of circumference 400 m, what is his displacement?

A body starting with initial velocity u comes back to the starting point in t seconds. Then the acceleration is

A train is travelling at a speed of 108 km/h. Brakes are applied so as to produce a uniform retardation of 1 m/s^2. Find how far the train will go before it is brought to rest :

The acceleration of an object moving in a straight line can be determined from the

Which of the following statements is correct for a particle travelling with a constant speed?

In a damped oscillator, the mass of the oscillator is m = 200g, force constant is K = 90N/m and the damping constant b is 40 g/s. Find the time taken for its mecharical energy to drop to half its initial value

On the distance-time graph, the Y-axis should be labeled as

A particle has a velocity u towards east at t = 0. Its acceleration is towards west and is constant, Let 

A body was initially moving with 10 m/sec and it starts acceleration with 2 m/sec ^2, the distance covered by it in 10 sec will be

Is it possible for an object's velocity to increase while its acceleration decreases?
