A particle moves in straight line. Acceleration of particle changes with velocity as showns in graph:

A particle starts from rest (at x = 0) when an acceleration is applied to it. The acceleration of the particle changes with its co-ordinate as shown in the fig. Find the speed of the particle at x = 10m .

Assertion : Acceleration of a moving particle can change its direction without any change in direction of velocity. Reason : If the direction of change in velocity vector changes, the direction of acceleration vector also changes.

Initial velocity and acceleration of a particles are as shown in the figure. Acceleration vector of particle remain constant. Then radius of curvature of path of particle :

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

Refering to v-s diagram, find: . a. Acceleration of the particle when its velocity becomes half of the initial velocity. b. Total distance covered by the particle.
