A Block Is Pulled at Constant Speed Along a Rough

Question 14

Multiple Choice

A block is pulled at constant speed along a rough level surface by a rope that makes an angle of 30° with respect to the horizontal. The applied force along the rope is A block is pulled at constant speed along a rough level surface by a rope that makes an angle of 30° with respect to the horizontal. The applied force along the rope is . The force of kinetic friction between the block and the surface is 10 N. -Which one of the following expressions gives the magnitude of the force in SI units?
