a)An object of mass ?m rests on a horizontal frictionless surface. A constant horizontal force of magnitude ?F is applied to the object. This force produces an acceleration: always only if ?F is larger than the weight of the object only while the object suddenly changes from rest to motion only if ?F is increasing choice A b)Now let there be friction between the surface and the object. If the object has a mass of 10 kg, and ??μs =...
