Question

A mass M slides on a horizontal surface. A mass m is attached to a string routed over a pulley as shown below Friction is present. When m is released, M accelerates to the right. The coefficient of friction between M and the surface is pk. Which one of the following statements is true? Doubling the mass of M will double mu k. Doubling the mass of M will halve the acceleration. Doubling the mass of M will double the force of friction. Doubling the mass of m will double the acceleration. mu k will increase as mass M accelerates.
