Net external force acting on a system of particle is not equal to zero. If velocity and acceleration of the centre of mass of the system of particles at some instant of time are found to be v and a respectively select possible option (s).

A system of particles is acted upon by a constant nonzero external force. If v and a are instantaneous velocity and acceleration of the centre of mass, then it is possible that at a given instant

A system of particles is free from any external force vec v and vec a be the velocity and acceleration of the centre of mass, then it necessarily follows that :

The velocity of a particle is given by v=12+3(t+7t^2) . What is the acceleration of the particle?

A particle moves with initial velocity v_(0) and retardation alphav , where v is velocity at any instant t. Then the particle

A system consists of two particles. At t=0 , one particle is at the origin, the other, which has a mass of 0.60kg , is on the y-axis at y=80m . At t=0 , the centre of mass of the system is on the y-axis at y=24m and has a velocity given by (6.0m//s^3)t^2hatj . (a) Find the total mass of the system. (b) Find the acceleration of the centre of mass at any time t. (c) Find the next external force acting on the system at t=3.0s .

A particle is moving in a circle of radius R in such a way that at any instant the tangential retardation of the particle and the normal acceleration of the particle are equal. If its speed at t=0 is v_(0) , the time taken to complete the first revolution is

At any instant, the velocity and acceleration of a particle moving along a straight line are v and a. The speed of the particle is increasing if
