To 0 2 x0 A block of mass m is on a rough horizontal surface and is attached to a spring with spring constant k The coefficient of kinetic friction between the surface and the block is u When the block is at position x 0 the spring is at its unstretched length The block is pulled to position x xo as shown above and released from rest The block then travels to the left and passes through x 0 before coming momentarily to rest at position xo 2 11 15 Which of the following is a correct expression for the kinetic energy of the block as it first travels through position x 0 A 0 B kx 2 C kx 2 umgxo D kx 2 3umgxo 2 Vansh P Single Person Usage vanshraaj
