Question

The potential energy of body of mass 5 kg moving in xy plan

Answer 1

The potential energy of a particle of mass 5 Kg moving in x-y plane is given as U = (7x + 24y ) j , x and y being in metre. Initially at t=0 , the particle is at the origin ( 0, 0 ) moving  with a velocity of ( 8.6i + 23.2j ) ms-1 . Then the velocity of the particle at t = 4s , is 5 ms-1the acceleration of the particle is 5 ms-2the direction of motion of the particle initially is at right angles to the direction of accelerationthe path of the particle is circle
