Acceleration

A particle starts its motion from rest under the action of a constant force. If the distance covered in the first s is and that covered in the first s is , then:
1.
2.
3.
4.

A particle moves a distance in time according to equation The acceleration of the particle is proportional to:
1. (velocity)
2. (distance)
3. (distance)
4. (velocity)

A body is moving with a velocity of towards the east. After its velocity becomes towards the north. The average acceleration of the body is:
1.
2.
3.
4.

The motion of a particle along a straight line is described by the equation where is in meter and in seconds. The retardation of the particle, when its velocity becomes zero, is:

The and coordinates of the particle at any time are and respectively, where and are in meters and in seconds. The acceleration of the particle at s is:
