A 5.510 kg block of wood rests on a steel desk. The coefficient of static friction between the block and the desk is u, = 0.605 and the coefficient of kinetic friction is µk = 0.205. At time t = 0, a force F = 20.1 N is applied m horizontally to the block. State the force of friction applied to the block by Us,k the table at times t = 0 and t > 0. 32.67 11.07 t = 0 N t > 0 N Incorrect Incorrect Consider the same situation, but this time the external force F is 40.6 N. Again, state the force of friction acting on the block at times t = 0 and t > 0. t = 0 32.67 N t > 0 11.07 N
