1a . A constant force of 32.3 N pulls on a 20 kg block on a horizontal surface. The force is directed at 30o above the horizontal. A friction force impedes the motion. If at the start of the motion the block was at rest and after 11 meters it has a velocity of 3, what is the coefficient of friction? 1b. What is the work done by the constant force when the block is moved 8 meters? 2.What constant,...
