A particle slides down along an inclined plane A C . If the plane is frictionless, kinetic energy of particle at C is

Step-by-step solution

Let the mass of the particle be m . If the particle slides from height y under the action of gravity, the velocity acquired by the particle is given by, v= 2 g y Hence, kinetic energy, KE = 1 2 m v^2 aligned & KE = 1 2 m( 2 g y )^2 & =m g y & aligned
