velocity of the particle. The motion of the particle takes place in a plane. It follows that
1) The kinetic energy of the particle changes with time
[1 ]
2) The acceleration of the particle is constant
3) The velocity of the particle is constant
4) The speed of the particle is constant
of the naner then​
