Is it possible that your cycle has a northward velocity but southward acceleration ? If yes, how ?

A : It is not possible to have constant velocity and variable acceleration. R : Accelerated body cannot have constant velocity.

A wheel is rolling on a horizontal plane. At a certain instant it has a velocity v and acceleration a of CM as shown in figure . Acceleration of

Two particles A and B start simultaneously from the same point and move in a horizontal plane. A has an initial velocity u_(1) due east and acceleration a_(1) due north. B has an initial velocity u_(2) due north and acceleration a_(2) due east. Then :

Two paricles A and B start simultaneously from the same point and move in a horizontal plane. A has an initial velocity u_(1) due east and acceleration a_(1) due north. B has an intial velocity u_(2) due north and acceleration a_(2) due east.

The position time graph for a particle moving along X axis has been shown in the fig. At which of the indicated points the particle has (i) negative velocity but acceleration in positive X direction. (ii) positive velocity but acceleration in negative X direction. (iii) received a sharp blow (a large force for negligible interval of time)?

Is it possible, that a body is moving with negative acceleration still speeding up? Given reason for your answer.

A body A starts from rest and moves with a uniform acceleration along a straight line. Another body B has some initial velocity and moves with larger acceleration than that of A . The correct velocity time graphs

A particle is moving due to eastwards with a velocity of 5 ms^(-1) . In 10 seconds the velocity changes to 5 ms^(-1) northwards. Calculate the average acceleration of the particle in this time.

(a) A particle is moving eastward with a velocity of 5 m/s. If in 10 s the velocity changes by 5 m//s northwards. What is the average acceleration in this time ? (b) What is the retardation of a moving particle if the relation between time and position is, t = Ax^(2) + Bx ? (where A and B are appropriate constants)
