Define instantaneous velocity of a particle?

If the instantaneous velocity of a particle is zero, will its instantaneous acceleration be necessarily zero?

If the instantaneous velocity of a particle is zero will its instantaneous acceleration be necessarily zero?

If the instantaneous velocity of a particle is zero, will its instantaneous acceleration be necessarily zero

Obtain instantaneous velocity of a particle executing SHM.

The instantaneous velocity of a particle is equal to time derivative of its position vector and the instantaneous acceleration is equal to time derivatives of its velocity vector. Therefore :

The instantaneous velocity of a particle is equal to time derivative of its position vector and the instantaneous acceleration is equal to time derivatives of its velocity vector. Therefore :

The displacement of a particle is given by x(t) = (4t ^(2) +8) meter. The instantaneous velocity of a particle at t = 2s is

The instantaneous velocity of a particle moving in xy-plane is vecV=(ay)hati+(V_(0))hatj where y is the instantaneous y co-ordinat of the particle and V_(0) is the particle starts from origin then its trajectory is
