Leeeee 0 M 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 When the block is at position x 0 the spring is at its unstretched length The block is pulled to position x 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 x x x 2 15 Which of the following is a correct expression for the kinetic energy of the block as it first travels through position 1 0 B x 2 C k 2 mgxo D kx 2 3 mgx 2 E kx 2 2 mgx the coefficient of kinetic friction A B C D kxo 4mg kxa 2mg 3kxo 4mg kxo mg 2k mg 17 Which of the following is a differential equation that could be used to solve for the block s position x as a function of times when it is moving to the left A m B m4 x C m sive D m E m kx mg kx mg kx mg Ax
