The potential energy U in Joule of a particle of mass 1kg

Last updated: 6/12/2023

The potential energy U in Joule of a particle of mass 1kg 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 t 0 then A The particle has constant acceleration B The work done by the force from the position of rest of the particle to the instant of crossing the x axis is 25 J C The speed of the particle when it crosses the y axis is 10 m s D The co ordinates of the particle at time t 4s are 18 28
