Calculate the magnitude of the normal force on a 15.2 kg block in the following circumstances. (enter your answers in n.) hint (a) the block is resting on a level surface. 15.2 incorrect: your answer is incorrect. n (b) the block is resting on a surface tilted up at a 25.8° angle with respect to the horizontal. 13.16 incorrect: your answer is incorrect. n (c) the block is resting on the floor of an elevator that is accelerating downward at 2.53 m/s2. n (d) the block is on a level surface and a force of 155 n is exerted on it at an angle of 25.8° above the horizontal.
