The drawing shows a large cube (mass = 21.0 kg) being accelerated across a horizontal frictionless surface by a horizontal force p. a small cube (mass = 4.5 kg) is in contact with the front surface of the large cube and will slide downward unless p is sufficiently large. the coefficient of static friction between the cubes is 0.710. what is the smallest magnitude that p can have in order to keep the small cube from sliding downward?
