A plank of mass m 1 with a bar of mass m 2 placed on it lies on a smooth horizontal plane. A horizontal force growing with time t as F = kt (k is constant) is applied to the bar. Find how the accelerations of the plank a 1 and of the bar a 2 depend on t, if the coefficient of friction between the plank and the bar is equal to µ. Draw the approximate plots of these dependences.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
When t ≤ t 0 , the accelerations a 1 = a 2 = kt / (m 1 + m 2 ); when t ≥ t 0
a 1 = μ gm 2 / m 1 , a 2 = (kt – μ m 2 g) / m 2 . Here t 0 =
