The potential energy v in joule of a particle of mass 1 kg moving in xy plane, obeys the law v=3x+4y, when (x,y) are the co-ordinates of the particle in meter. If the particle is at rest at (6,4) at time t=0, then

Answer»

The PARTICLE has constant acceleration
the work done by external force from the position of rest of the particle and the instant at which the particle crossign x-axis is 25 joule
the speed of the particle when it corsses the y-axis is 10 m/s
the co-ordinates of the particle at time t=4S are (-18m,-28m)
