Question

Calculate the magnitude of the normal force on a 17.7 kg block in the following circumstances. (Enter your answers in N.) (a) The block is resting on a level surface. The four cases in this problem are the most common situations. In general, solving for the normal force involves drawing a free-body diagram and applying Newton's second law. N (b) The block is resting on a surface tilted up at a 25.8° angle with respect to the horizontal. (c) The block is resting on the floor of an elevator that is accelerating downward at 3.03 m/s^2. (d) The block is on a level surface and a force of 165 N is exerted on it at an angle of 25.8° above the horizontal.
