    Friction with moving block question

    The drawing shows a large cube (mass = 49 kg) being accelerated across a horizontal frictionless surface by a horizontal force P. A small cube (mass = 4.6 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...
