The potential energy U in joule of a particle of mass 1 kg moving in x-y plane obeys the law U = 3x + 4y, where (x, y) are the co-ordinate of the particle in metre.
If the particle is at rest at (6, 4) at time t = 0 then the particle has constant acceleration, the speed of particle when it crosses the y-axis is 10 m/sand co-ordinate of particle at t = 1 s are (4.5, 2).
The particle has no zero acceleration.
